Core Erlang improvements

[renzhexiangjiao]

Hi, I made some changes to the erlang library and I would be grateful if you could review them. These changes involve only the Core Erlang side of the library as I noticed it's incomplete and it's something I need for my own project (I'm working on a compiler to Core Erlang).

I added the following features:

• Core Erlang lexer
• Core Erlang parser
• Core Erlang printer
• some modifications to the Core Erlang AST to better reflect this specification

If you like these changes enough to merge them into your project, it would help me greatly if you re-released the erlang library so that I can install its new version from opam in my own project.

Thanks, Franek

Hi! Thanks for the contribution. I think we should split up the erlang library out of this repo since I am not actively working on Caramel anymore. In the meantime, I'll merge your improvements to it.

Feel free to join the Discord so we work out how to publish a new version: https://discord.gg/yvCcjNmCcY
