I have a proto file that has a few imports on proto files in other packages and readProtoFiles simply blows up with errors because it doesn't know where to find the imports.
readProtoFiles2 was introduced to fix that issue eddelbuettel/rprotobuf#39 and https://www.rdocumentation.org/packages/RProtoBuf/versions/0.4.14/topics/readProtoFiles. So can read_services use readProtoFiles2 and allow us to specify proto_path?
