Goals:
1. Use an exact `git tag` version, like v1.0.0, when clean
2. Translate the `git describe` version (v1.0.0-4-g0000000)
to semver (v1.0.1-pre4+g0000000) in between releases
to semver (1.0.1-pre4+g0000000) in between releases
3. Note when `dirty` (and have build timestamp)
Fail gracefully when git repo isn't available.
