BREAKING CHANGE: The `STANDARD_ENCODING` const is now under `Encoders` instead of `Encoder` which may lead to undefined const errors if you are using this const for some reason.
…ment Let's add it to `Encoders.new` for backward compatibility.

I noticed that in the base64 gem, the method tr has a bang in the if branch, but not in the else branch 🤔

Interesting! I'll open a separate PR to fix that 🙂

Details
This PR introduces the new
Encodersmodule in order to encapsulate the logic of the different encoding methods into the same place and let us re-use this logic in across all the different parts of the gem which will in turn allow us to cleanly (and finally) remove thebase64dependency. This logic was previously encapsulated inEncoderwhich now will just delegates encoding and decoding tasks to specific encoder classes defined in the newEncodersmodule - we are really just keeping it, just in case, for backward compatibility.The new
Encoderscontains classes forBase64Encoder,Base64UrlEncoder, andNullEncoderand alookupmethod to return the appropriate encoder class based on the encoding type.Finally, it also updates the different parts of the gem where the
base64gem was used.
