Gcmlib

Updates:

- Dependency updates.

Update:

stringD() will now return bytes type (or whatever "plaintext" is, instead of trying to .decode() "plaintext" then return it.

The user/you can decide how to decode it with whatever ISO you want instead of trying to fight with whatever I decide to have it be .decode() - ed as.

(I am making this change because it is conflicting with a project I am working on.)

Changes
> 12/31/22
- GCMlib now uses Argon for its kdf instead of scrypt.

Making my library of functions public. Also to make it easier in other projects to use this encryption method instead of having to make everything all over again. I can now just import everything.
