Convert Stage to a Protocol

Browse source 
The Stage is now implemented as a runtime-checkable Protocol.

Part of this led to the realisation that we can't create a DirectThingClient
based on a Protocol, only on a concrete Thing. While it might be
a good idea to address that in LabThings in due course, for now
we work around it by creating both a Protocol and a stub class. The stub class implements the protocol, and
can be used to declare a dependency.
