Add standard + typescript linting

[taoeffect]

Problem

No linter.

Solution

First close #1.

Then take a look at how this repo does linting, as it's now setup to do standard + TypeScript: https://github.com/okTurtles/chel

Add a deno task lint command, and have it run as part of the github actions (you'll need to copy & add this file) that run when PRs are submitted.
