feat: split out code

* Splits implementations out from interfaces so we can depend on interfaces module without pulling in crypto, etc (fixes #110)
* Converts code to typescript (fixes #101)
* Adds types for PeerData and Registrar - these will need to be fleshed out properly in a subsequent PR

BREAKING CHANGE: not all fields from concrete classes have been added to the interfaces
