JavaScript tooling

Nobody has claimed this yet.

Hey @lucmos thanks for writing this package, it's just what I was looking for!

This was my first dabble with plasma, so I spent some time setting up my regular JS tooling for it (TypeScript, ESLint, prettier, etc) and reformatting the code slightly. I've not opened my changes as a PR because they were really just for me, but if you're interested in a PR I'd be happy to clean them up and send one through. If you're not interested (which I'd completely understand! who needs a build-step for something simple like this?!) feel free to just close this issue.

My fork is here: https://github.com/benjie/UltrawideWindows

The main code you'd care about is in `src/main.ts`: https://github.com/benjie/UltrawideWindows/blob/13152e8bf2450556d38ea81804eef746c22299fe/src/main.ts#L153-L598

(Don't worry about the type definitions above line 153, they'll be factored out at some point.)

Cheers!

PS: do you know, where's the canonical documentation of API this JS code consumes?

Review src/main.ts and the linked fork's tooling changes first, then confirm whether adopting TypeScript, ESLint, and formatting/build tooling is wanted. Done would be a maintainer-approved tooling change, with the canonical API documentation source identified.
