JSON convenience wrapper

[peterboyer]

Very commonly use JSON.parse and JSON.stringify and always need to wrap them with fromThrowable.

Ideally want to be able to:

import { JSON } from `@armix/terror/json`;

const $request = JSON.stringify(...);
const $response = JSON.parse(...);

To have access to .parse and .stringify both as fromThrowable functions, and then prototype onto the default JSON object to fallback to anything else (for better future useability).
