Can I add/modify protobuf import path?

[Reasno]

Thanks for making this awesome tool.

It would be very helpful to allow users to add -I option to specify the import path for the protoc command underhood. Or even better, allow users to add any additional protoc arguments.

We agree! At the very least in 1.0 of truss we want to behave much closer to a wrapper of protoc and allow passing through any arguments. Some if not all of this should be achievable now, adding -I seems feasible.
