feat: basic d.ts file (#161)
`protocol.d.ts` had to move to `protocol.ts` otherwise typescript refuses to include it in the out directory. Removed the old d.ts generator. It will need to be rewritten anyway. These new types include private stuff that they probably shouldn't, and are missing documentation. I'll follow up with a better d.ts generator later. #6
