coadds: add options to filter targets while coadding #888

Open sbailey opened 4 years ago

sbailey commented 4 years ago

Add options to filter by target bits while coadding, e.g. to produce separate coadd files for QSO targets vs. LRG targets. Syntax would be something like:

desi_coadd_spectra \
    --target-column CMX_TARGET \
    --target-mask SV0_QSO,MINI_SV_QSO ... \
    {input cframe or spectra files to be coadded...}

If --target-column isn't specified, use desitarget.targets.main_cmx_or_sv to derive what flavor this likely is from the input fibermap (which inherited columns from the input targets so this should work).

Moving this from the minisv2 project to the Development-2020 project since it isn't critical to have for minisv2 and we'd like to launch today.
