ANN: Nix derivations


#1

I’ve created Nix derivations for the essential reason tools* and put them all in a repo :point_down:

It’s still very much WIP but the most important things (bsb, reason-language-server, esy…) seem to be working.

*I’m still very new to this ecosystem so feel free to PR or create an issue if there’s an important tool missing!
