Update SMTP authentication mechanisms and related tests
Introduced the SMTPAuthNoAuth mechanism in the auth.go file meant for instances where authentication is not required or supported. Adjusted tests in client_test.go to account for this new mechanism. Minor order modifications were also made to the list of supported SMTP AUTH types and respective tests for better consistency.

Closes #176

Add support for HTML alternative message body
The code has been updated to allow for an HTML alternative to the plain text body in messages. This includes adding a new function to add this alternative body along with additional unit tests to ensure the multipart messages are properly constructed. The tests also check the correct usage of different charsets.

Add charset related tests and functionality
New unit tests have been introduced for WithPartCharset and SetCharset methods in part_test.go. Also, a GetCharset method has been implemented in part.go. These modifications ensure the robustness of charset handling within the application.

Add Charset support for message parts
Charset support has been added in the 'Part' struct. A 'SetCharset' method and a 'WithPartCharset' option have been added to override the default Part charset. The 'writePart' function in msgWriter now accommodates the charset defined at the Part level, defaulting to the previous functionality if not set.

Upgrade codecov-action to v3 in GitHub workflow
The codecov-action version used in the GitHub workflow file has been upgraded from v2 to v3. This enhances the reliability and performance by leveraging the new features and improvements available in version 3. This commit doesn't affect the functionality of the project but is more of a dependency update.

#105: Add default ports and fallback behavior for SSL and TLS
Introduced default ports for SSL/TLS and STARTTLS connections in SMTP client. Also added fallback behavior, allowing the client to attempt connections on port 25 using plaintext if secured connections fail. Deprecated old methods and implemented new ones to enforce these changes effectively.

This is a copy of the PR muhlemmer:enhance-default-tls-port by @muhlemmer. Since they unfortunately didn't reply in the PR anymore I cloned the PR. They will be fully attributed in the PR, though.

#166: Add delivery status indication for messages
This update introduces a new property, `isDelivered`, in the message struct to track if a message has been successfully sent or not. Additionally, this also includes a new helper function `IsDelivered` to easily retrieve the status. This feature enhances the tracking capabilities of outgoing messages across different client files.

Add null check to prevent empty file handle error in msg_test.go
Implemented a null check to ensure the 'fi' file handle is not empty. With the absence of this check, the test was continuing even when 'fi' was empty, leading to null pointer exceptions further down in the code.

Fix potential null pointer exceptions in msg_test.go
Added robustness and improved error handling in msg_test.go by adding null checks before calling values from the genHeader map in RequestMDNTo and related functions. This enhancement was necessary to avoid the operations on non-existing keys and potential null pointer exceptions.

Improve error handling in msg.go
Added additional checks when calling values from the genHeader map in msg.go file. This is to prevent trying to operate on non-existing keys, hence avoiding possible null pointer exceptions. The checks ensure the key HeaderMessageID exists in the genHeader map before attempting to operate on it. This is essential for functions like RequestMDNTo, RequestMDNToFormat, and RequestMDNAddToFormat, thereby improving the robustness of the code.

Protect against key not found in genHeader map in msg.go
Added checks to ensure the key HeaderMessageID exists in the genHeader map before attempting to operate on it in msg.go. This will prevent possible null pointer exceptions when trying to assign the key a value or append it to the mids slice.

Add checks for nil or empty Subject headers
Added condition checks in `msg_test.go` for nil or empty Subject headers in the assigned functions. If the Subject is found to be nil or its length is less than 1, an empty string is now appended to prevent issues arising from null pointers or non-existent Subject headers in email messages.

Fix null pointer exception in Is function
Updated the Is function in senderror.go to handle null values for SendError. This was done by adding a nil-check for surfaced pointer errors in the errors.As call. This prevents the function from attempting to derive values from a null pointer and consequently prevents null pointer exceptions from being thrown.

Handle nil buffer in Reader and update tests
Updated the Reader struct in reader.go to properly handle nil buffers. This prevents potential errors from nil pointer dereference. Also added the fmt package for debugging purposes. Correspondingly, additional tests in reader_test.go were also added to cover these edge cases and ensure the Reader struct correctly handles them.

Update range loop to improve msg function readability
Converted the range loop in the GetAddrHeaderString function in msg.go to use value semantics rather than index notation. This improves code clarity by not unnecessarily referring to m.addrHeader[h] in the loop and instead referencing the value directly (using variable mh), making it easier to understand and maintain.

"Improve error checking in SMTP client creation"
A change was made in the SMTP client creation process to add more robust error handling. The new logic checks if the client is null after being created and, if true, returns an error. This update can help prevent potential null pointer exceptions in runtime, ultimately leading to more stable application.
