Update README with new features and clean-up goreleaser config
Updated the README file to document new features added in the codebase: codecov badge, pre-built package usage, fixed-length password flag usage, coinflip mode, and the minimum required characters. The goreleaser configuration (`.goreleaser.yaml`) was cleaned up, removing unnecessary sections for docker usage. This clarifies how to execute certain functionalities and makes the goreleaser configuration easier to read and maintain.

### Coinflip mode
|
||||
Sometimes you just want to quickly perform a simple, but random coinflip. Since v2.0.0 apg-go has a
|
||||
coinflip mode, which will return either "Heads" or "Tails". To use coinflip mode, use the `-a 2` argument:
|
||||
```shell
|
||||
$ ./apg -n 10 -a 2

### Minimum required characters
|
||||
Even though in apg-go you can select what kind of characters are used for the password generation, it is
|
||||
not guaranteed, that if you request a password with a numeric value, that the generated password will
|
||||
actually have a numeric value. Since v2.0.0 apg-go has a new set of arguments, that let's you define
|
||||
a minimum amount of characters of a specific character class to be included in the generated password.
|
||||
This can be requested with the `-mL`, `-mN`, `-mS` and `-mU` arguments. Each stands for the corresponding
|
||||
character class. If one of the arguments is give, apg-go will generate passwords until the requested amount
|
||||
of characters of the corresponding class is given.
|
||||
|
||||
**Note on minimum characters**: Please keep in mind, that due to the way the "minimum amount" feature works,
|
||||
the calculation time for passwords can increase and if the amount is set too high, it can result in apt-go
|
||||
never being able to finish the job.

||||
