Remove need for git lfs to store large files

- Reduce the size of the regression files for testing geometry objects
- Don't save geometry objects when testing geometry commands. This means
  the regression check is done using the receiver output rather than
  reading the geometry directly. Some tests still output the geometry
  for reference (useful if tests fail to check the geometry that was
  built).
