Hello wasm proof-of-concept project

Try to see if Dragit can be running in a browser.

1. try to run peer discovery using Rendezvous protocol
2. take discovered peers and use libp2p WebRTC to initiate connection between them
3. finally, use Dragit protocol to transfer files between peers

Watch out: this is experimental project. Expect dragons here.

TODO:

• discovery by namespaces: preferably rendezvous server side
• webrtc dialing
• dragit protocol on webrtc
