[ANN] Brushless - DynamoDB expressions builder

Hey, :wave:

I’m excited to share my first attempt at creating something useful in ReScript.

It’s called Brushless (apologies for the lack of creativity), and it’s a set of low-level utilities for writing DynamoDB expressions. My main goal was to allow me to write type-safe expressions that are equivalent to hand-written ones in TypeScript land, and to do so with zero dependencies (which I accomplished with a few small hacks). This way, my coworkers would have no excuses not to use it, and I could slowly bring them over to the **dark side of ReScript **.

I’m fully open to any feedback!
