unable to compile protocol buffer `test_runs.proto`

i downloaded latest zip from which has following uncompiled protocol buffer files

openhtf-master/openhtf/output/proto/guzzle.proto
openhtf-master/openhtf/output/proto/test_runs.proto

i install this latest zip using in virtualenv using `python setup.py install`

./venv/lib/python2.7/site-packages/openhtf-1.3.0-py2.7.egg/openhtf/output/proto/guzzle.proto
./venv/lib/python2.7/site-packages/openhtf-1.3.0-py2.7.egg/openhtf/output/proto/test_runs.proto

1) it would be nice if you distribute compiled protocol buffer files (as well)
2) I am unable to compile the ` test_runs.proto` and getting following errors

```(venv) [antman@joke-lab proto]# protoc -I=. --python_out=. test_runs.proto
google/protobuf/descriptor.proto: File not found.
test_runs.proto: Import "google/protobuf/descriptor.proto" was not found or had errors.
