Add format github action for proto files (#57)

This PR establishes that we should use the Google style of formatting
for proto3 files, with line-end breaks happening at 120 characters (a
decent line ending break in the era of 1080p and 4k). It also installs a
github action that will enforce the formatting and throw when things are
not formatted

@devs: to get the right formatting on your PRs you can do the following
- add to your visual studio settings.json:
```json
"clang-format.style": "{BasedOnStyle: Google, ColumnLimit: 120}"
```

to run one massive format run on everything you can do:

```bash
find . -name "*.proto" | xargs clang-format -i --style="file:./.clang-format
```
