Add node/browser lib for Lucy

[mattpocock]

import { parseToJson } from '@lucylang/node';

const machine = parseToJson(
`
// Lucy file in here
`
)

Many use-cases for this - JS runtime, browser-based tooling, all sorts of cool stuff.

Is this the same thing as #16 ?

@matthewp Yes! I guess it is the same discussion, just different API. I'll close this and replicate my comment.
