- read_targets, write_targets is now in ptv.py
- we can read complex image file names but we write always simple target files `f'cam_{id:d}.{frame:d}'`
- bump_version can be used to update versions, use 'major', 'minor','patch'
- last patch is 0.3.0
- in parallel we updated `test_cavity` so take a look there
