MultipeerAdapter is appropriate to use when the host environment has no authoritative
server simulation, where each client owns some part of the simulation, and a connection from each client to the Mixed
Reality Extension (MRE) app is necessary. The MultipeerAdapter serves as an aggregation point for these client
connections. This adapter is responsible for app state synchronization to new clients, and for managing distributed
state ownership (i.e., which client is authoritative over what parts of the simulated state).
Start the adapter listening for new incoming connections from engine clients
