Hello mutiple reviewers: this is basically just a bunch of config changes, all of which seemed, whilst Erik Dennihy and I worked on them, to be necessary, and that we feel should now be merged to form the base of the "DRP" config for the AuxTel imaging survey (though doubtless config-twekaing tickets will be required soon to improve upon this, so don't expect this to work for all things all the time, but it's a big step in the right direction). I wanted to get multiple eyes on it though, as we could easily be doing something we don't really want to here, so wanted to check with multiple, experienced people who know many different areas of the pipelines. Let us know your thoughts!

Initial PR for obs_lsst was closed before merging due to user branch merge error (https://github.com/lsst/obs_lsst/pull/373), new branch and associated PR here (https://github.com/lsst/obs_lsst/pull/400)

Thanks for all the changes. The final result is a concise set of LATISS-specific configs.
