Standardize on URI scheme for linking to groups

[writerly03]

Extend URI scheme for also adding data repo keypair for migrating devices

Mauve to provide instructions for this later in the week (ignore for now)

So here's what we need to store in the URL:

• dht key
• encryption key
• owner public key
• owner secret key

I propose we do something along the line of magnet links like this:

save+dweb:?dht={dht}&enc={encryption}&pk={public key}&sk={secret key}

I think we should use hex encoding.

The front end of the app doesn't need to parse it, just needs to register the protocol handler and pass it to the backend

Mauve has the proposal for the URI scheme; Richard need to register the above in the app so that the app launches when the link is clicked.

Hypha will have their piece completed by EOD (Tuesday).
