Protobuf files

How to add a new protobuf file

1. Create a few called <package_name>.proto in protos/
2. Make sure to use the same "package" pragma as the file name in the body of the proto
3. Specify any message schemas in that proto file.

How to use the resultant protobufs:

This package will automatically generate modules that contain all your message structs. So given a file called foo.proto with message Bar, your crate can import the generated struuct like so:

use pb::foo::Bar;
