Astrohack

- General:
- Fixed issues with problematic scape sequences.
- Moved user documentation pages from the wiki to the readthedocs.
- Misc improvements to readthedocs page.

- FITS Comparison tool:
- Fixed bug caused by a typo.
- Added new types of plot: Reference image plot and unresampled data plot.
- Added statistics to the headers of all plots.
- Created a function to extract RMS values from an FITSImage obj: rms_table_from_zarr_datatree.

- Panel:
- Fixed a bug that prevented old files with no polarization state information from being opened.

General Changes:
- Dropped support for Python 3.9 as the latest release of xarray drops support for this python version
- Added support for Python 3.12, this python version was not support by python-casacore for a long time but that is no longer the case.

Panel:
- Introduced a new parameter called exclude_shadows.
- This parameter activates using a mask which also excludes the shadows caused by the quadrupole holding the secondary.

Image Comparison Tool:
- This release introduces a simple FITS comparison tool to gauge the differences between apertures taken at different epochs and software such as AIPS.

This release includes the release of the Cassegrain ray Tracing tool.
More information about this tool can be seen at our readthedocs page:

This release bring a bug fix for locit:
- When a delay fit failed locit was crashing, there is now error trapping around the fitting routines giving out a warning when a fit fails.

This is a patch release, that brings a bug fix to HOLOG:

- After the phase fitting process the phase corrections were subtracted from the phase image without wrapping the phase to the - $\pi$ to $\pi$ interval, this has now been fixed by the addition of phase wrapping at the end of the phase fitting process.
- A test has been added to panel to detect images from HOLOG that have been produced with astrohack versions previous to this one to trigger a phase wrapping of the input phase image before computing deviations.

This release brings some improvements to LOCIT:
- It is now possible to use 'RL', 'LR', 'XY' and 'YX' to describe the polarization to be used, 'both' is still accepted as well.
- LOCIT no longer crash in the event of missing data, it will produce a warning instead.
- If all data for an antenna DDI combination is missing during processing due to filtering (e.g. low elevation data) LOCIT will now produce a warning.
