TS Module imports should use tsconfig path map

[machuu]

tsconfig.json can map paths within the project directory tree. TS Handbook path-mapping

In this project, the first place I want to use this is test files.

Currently, to import a TS module from src/ directory, I have to use

import { Card } from "../src/card"

Adding something like:

"basedir": ".",
"paths": {
  "~src": ["src"],
  "~test": ["test"]
}

would let me import files in <project root>/src, like:

import { Card } from "~src/card"

from any depth in the project directory.
