Support arbitrary URI schemes

[ngirard]

The only supported protocols are currently http, https and tcp.

I need to be able to specify other URI schemes than http and https. For instance, I wish to be able to specify

weave '8088/id/(id)' to 'note://(id)'

This currently results in the following error

[2020-11-01T08:46:17Z ERROR weave] failed to parse routes: 'note://(id)' is not a valid destination location: note is not a supported protocol

Could this be implemented ?

Cheers
