ska3-matlab 2023.8

This PR includes:

A list of packages is being removed from ska3-flight. These packages, which have a narrow scope an audience, will be grouped in a separate category and installed separately. In order to improve flexibility and reduce unnecessary labor of full FSDS review, these packages will be delegated from FSDS control to a lower level (see here)
One new package: chandra_limits, a package for limit management.
Changes to proseco, sparkles and starcheck to make the ACA penalty limit optional.
Changes in parse_cm to handle machine-readable comments (see here)
Small updates to improve chandra_models access, including a change to xija so it will use ska_helpers.chandra_models.
changes in agasc to handle a HEALPix-index catalog
allow specifying the AGASC file/version in proseco and sparkles (in preparation for AGASC 1.8)

Interface Impacts:

11 packages removed.
parse_cm.or_list.read_or_list is deprecated. parse_cm.or_list.read_or_list_full should be used instead. Use of parse_cm.or_list.read_or_list will result in a warning.
parse_cm.common. _coerce_type is deprecated. Use ska_helpers.utils.convert_to_int_float_str instead.
xija models now will respect the CHANDRA_MODELS_DEFAULT_VERSION and CHANDRA_MODELS_REPO_DIR env vars end determine which model is used.
