Expand MapeoRPC to handle connections to local peers, and rename to LocalPeers

[gmaclennan]

Description

Working on the integration of LocalDiscovery and MapeoRPC for sync, I'm ending up with pieces of code throughout both MapeoManager and MapeoProject tying the pieces together. The sharing of peer names must update a peer list held somewhere, so we can expose listLocalPeers.

I think it makes more sense to encapsulate the code in a slightly modified version of the existing MapeoRPC class, handling device info events internally to update a property on the peer class and exposing the protomux instance so we can use the peers from here for sync / replication in project instances.

Public methods:

• sendInvite()
• sendInviteResponse()
• sendDeviceInfo()
• disconnectAllPeers() -> to be added post-MVP

Events:

• peers - when the connected peers changes
• invite - when an invite is received
