Add CI to update protobufs

[Maniktherana]

This is something we may overlook when implementing a feature, best to automate it.

Considerations:

• It should copy the latest protobufs from https://github.com/ditsuke/go-amizone and paste it into /proto/amizone.proto
• It should then run make gen commands
• After generating /gen/amizone_pb2_grpc.py, it should change line 5 from import amizone_pb2 as amizone__pb2 to import gen.amizone_pb2 as amizone__pb2
