[ANN] Reforging the ReScript Build System

It’s more about the configuration than the compilation speed.
Probably caused by many totally different projects, I have no idea about the best way to set these up.

• tsc vs tsc --build?
• Using the incremental flag or not?
• Using path aliases?
• In some projects I have to import files with the extension import { ... } from "./something.js", in some other projects I don’t.
• Should I use nx, turborepo, lerna, …?

I don’t like to say “skill issue”, but yeah… it’s a skill issue.

In rescript, I just have to add the dependencies to my rescript.json. Done.
