With the SetHeaderPreformatted() method we have the ability to set headers that are already preformatted by the user and will not be altered in the mail message output
For middlewares to be able to access the fully written mail message, we need a way to execute WriteTo without the calling middleware to be handled, otherwise we end up in an infinite loop
Therefore, this PR introduces the MiddlewareType and the corresponding change of the Middleware interface. We now require to return the MiddlewareType when the Type() method on the interface is called
This way we can also introduce the WriteToSkipMiddleware method which takes a MiddlewareType as argument. This will allow us to use a WriteTo call with the initiating Middleware to be skipped
- Added `EmbedFromEmbedFS()` to allow embedding from embed.FS
- Added `AttachFromEmbedFS()` to allow attaching from embed.FS
- Added `fileFromEmbedFS()` as internal method for both other m
methods to attach/embed the embed.FS file

We were using `io.Copy` to write to the body string/alternative string to the io.Writer. This placed the byte position of the buffer to be at the EOF after the first `WriteTo()` call leaving the output of a 2nd call to `WriteTo()` empty.
