Astrohack

Correcting previous release

This release adds a new method of gridding the visibilities onto a beam.
This method uses the convolution of the visibilities with a gaussian kernel with a size similar of the primary beam.
This is a fast release to attend to VLA validation needs, no documentation on the gaussian convolution gridding is provided at this point.

- General
- Dropped support for python 3.8, prompted by drop of support for 3.8 in graphviper
- Pixel coordinates now reflect the middle of the pixel rather than its left edge
- U and V axes are now always in meters in data files rather than in kilo lambda

- Combine
- Fixed weighted combining of DDIs

- Holog
- Refactoring for better separation between beam gridding and aperture generation
- Padding with zeros now produces images that have a size of 2^(ceiling(log2((original_size*padding_factor)))
- image_mds.plot_apertures can now choose polarization state
- image_mds.plot_beams plots are now split by polarization state
- Beam gridding using a gaussian kernel
- Bug fix: Calling holog with a grid_size and cell_size no longer overwrite these values in the input .holog.zarr file

- Panel
- Screw adjustments file now contains the method use to fit the panel and if it was a fallback
- Polarization state selection with I being the default

- ALMA Near field support (Alpha)
- ALMA NF ASDM filler to the .holog.zarr format
- Selection of ALMA OSF pad in holog to determine distance and defocusing
- Beam apodization
- Non-fresnel terms in aperture generation (Not fully correct)
- Phase near field corrections (Not fully correct)
- GILDAS\CLIC like phase fitting including astigmatism
