Future addition of workflows to work on NISAR RSLCs/GSLCs

[shitong01]

As followed up by the discussion here: isce-framework/dolphin#97 (reply in thread)

Perhaps an addition to sweets to incorporate NISAR RSLC coregistration / RIFG interferograms stack from ISCE3 workflows?

What about NISAR GSLCs? (I noticed slight differences in .h5 flavours for NISAR GSLC h5 products vs OPERA CSLCs / COMPASS generated S1-GSLCs)

Not sure if this is within this packages' scope, but in-built functions in sweets for downloads (dem, data etc) are useful for stack processing and can benefit users who would like more autonomy in geocoding/interpolation etc.

re-bumping this question as a reminder to check in a ~month after NISAR products become available
