Add TypeScript typings

[SimenB]

It would be very nice if this module came with TS typings 🙂

I've marked this as an enhancement issue and will leave it open here. If anyone would like to contribute please do.

I was gonna send a PR since the types aren't too advanced, but it seems the functions are different between CJS and ESM with CJS having parse and ESM having {init, parse}.

Thoughts on changing the API to be the same across module types? I.e. changing CJS to

module.exports.parse = parseCJS;
module.exports.init = () => Promise.reject(new Error('init is not supported when using CommonJS'));

Could potentially just no-op in the last one, or warn?

@SimenB I can get behind unifying the APIs to do that sure. That sounds like a good suggestion to me.

[SimenB]

Cool. I can send a couple of PRs tomorrow if you don't get to it.

Current thinking is init should just be Promise.resolve() so you know you can always call it. Without worrying about what API

Some time freed up tonight, so sent #27 & #28 👍

Thanks for the PRs! I've published a 0.6.0 with these.

Thanks @guybedford!
