chore: Convert repo to a monorepo

[chrstph-dvx]

Summary

Split the logic into 2 different packages:

• sdk containing most of the utilities function used by cli. The package meant to be used externally
• cli the CLI generating the different token lists. The package meant for internal use, generating lists

Steps to test

All scripts should be working in cli should be working and produce the same token list as previously.

Thanks for putting this together!
Few things we should probably touch base on:

• There's a few important changes currently on these branches that i want to make sure don't get lost.
• My assumption would have been that the sdk package is the one that would be consumed externally, i.e., this would surface methods that other projects would use to generate / manage their own token lists, and the stuff more specific to OCL's needs would be siloed off elsewhere in a separate package (I haven't actually reviewed the code yet, so maybe it's already on track with what I had in mind)
