add files from protozmq

[dneise]

Work in progress

Starting to add protozmq into this repo, so one gets both packages together.

These files are in principle duplicated in both packages protozmq and protozfits

CoreMessages_pb2.py
L0_pb2.py
R1_DigiCam_pb2.py
R1_LSTCam_pb2.py
R1_NectarCam_pb2.py
R1_pb2.py

but it turns out, they are not exactly identical. So I guess one of them is outdated.
