JP-3682: split outlier detection into separate steps for each mode

Closes #8634
Closes #7817

This PR addresses splitting outlier detection into separate steps for coronagraphy, IFU, imaging, spectroscopy, and TSO data. This was motivated by large differences in input parameters and algorithms that are implemented for each mode. The parallel separation of the documentation for those modes should also resolve the confusing structure of the docs for outlier detection.
