Pytom-match-pick

What's Changed
* `import pytom_tm` now has a `pytom_tm.__version__` attribute
* jobs are now annotated with the module version number
* the symmetry option is now specific about only covering rotational symmetry around the z-axis
* whitening filters are now stored to prevent recalculation

**Full Changelog**: https://github.com/SBC-Utrecht/pytom-template-matching-gpu/compare/0.3.0...0.3.1

Functionality updates to `pytom_match_template.py`:
- The `--per-tilt-weighting` option has been expanded so it can now model a 3D CTF with tilt and dose weighting (as previously described in methods like Relion subtomo averaging, Warp, and EmClarity). To enable the full weighting 3 files need to be provided: a .rawtlt/.tlt file with tilt angle info, a .defocus/.txt file with per tilt defocus (in nm), and a file with accumulated dose per tilt (in e-/A2). The defocus file and dose file are assumed to have the same ordering as the tlt file. PR 53
- Spectrum whitening is now available (similar to Rickgauer et al., (2017) for 2DTM). The power spectrum radial average is estimated for the full tomogram, and the whitening filter is calculated from it and applied to tomogram and template. It sharpens the correlation peaks! PR 53
- There is now a rotational-symmetry option to reduce the angular search for templates with rotational symmetry. PR 55
- It is now possible to provide a custom angular search file. PR 56

Fixes:
- `pytom_create_template.py` has a more specific warning message for the low pass filter. PR 51

Docs will be updated soon and we are working on a tutorial!

Thanks rdrighetto for some very useful discussion on the CTF model.

Most important updates
- starfiles written out by this module now contain all the extraction statistics and header start with `_ptm` (43)
- tomographic mask to extract particles within cellular regions can now be applied during candidate extraction (42)
- a fix has been added to make the testing of parallel jobs numerically stable (40)
- a few IO fixes for MRC files to make reading more permissive (33, 38, 41)

Thanks to hamid13r for the great feedback!
