Photometric redshifts in romancal

[stscijgbot-rstdms]

Issue RCAL-947 was created on JIRA by Mairan Teodoro:

We need to compute photometric redshifts for sources detected in images from Roman. We will use the LePHARE photometric redshift algorithm, as implemented in the RAIL project, to do this estimation. The code will accept Roman catalogs and output photometric redshift information (redshifts, uncertainties, flags, PDFs).

The first step of this process should be to install rail / LePHARE and start computing some photometric redshifts from existing catalogs and filter sets they provide. Then we should build in Roman filters and work on the interface between the Roman catalogs and the rail wrapper.
