Repurpose into gRPC servicequillback_17.0.0quillback/17.0.017.0.0

Repurpose repository into a spiritual successor of the previous
binding.  The backend code is retained behind a new gRPC API
defined in protos/radio.proto.  The simpler synchronous gRPC API
had been used for expediency, this may warrant revisiting to
rework into an async or callback API based server instead.  As
well, authentication has been left until some consensus on an
approach can be worked out.

-	TODO:
-		at this point:
-			- complete the set stereo_mode verb.
-			- find a way to tell the service which i2c chanel is used.
-			- separate the functions of driver from the verbs by creating new c file.
-			- find a way of monitoring the quality of tuning and correct it time by time.
-			- use Interupt for getting RDS data
