Lightcurver

- Better magnitude error bars
- HTML curve shifter generated as report at the end of pipeline

Various improvements, refactoring.

Breaking changes:
- Has new config.yaml entries, will crash when run with older config.yaml templates. (But will list the missing entries).
- Changes in the naming of the outputs of the automatic ROI modelling

- added masking of bad columns during cutouts creation with `ccdproc`
- hdu selection in config for data and headers
- servers with no internet connection: importing gaia only when necessary to avoid timeouts on runs where querying stars is already done.
- output wcs in automatic modeling fits products

Post-JOSS review release

- Absolute photometric calibration with Pan-STARRS in addition to Gaia
- added a simple script interface:
`lc_init` to quickly setup a working directory
and
`lc_run /path/to/config`
to run the pipeline.
- various bug fixes

Added support for position dependent distortion of the PSF. The pipeline now tracks the positions of all extracted cutouts in all frames, as uses this information to fit a position-dependent affine transformation (shear + stretch) of the PSF models.
Will break with older reductions, need to re-extract the regions file.
