Add metadata to the reference alignment catalog

[mdlpstsci]

Also, reconsider the name of the catalog as it currently includes a detector and flt or flc substring. However, this file represents the entire single visit which may use multiple detectors and have both flt and flc files. The current naming convention is:

hst_proposalID_obsetID_instrument_adetector_[flt|flc]_metawcs_all_ref_cat.ecsv hst_11665_06_wfc3_ir_flt_metawcs_all_ref_cat.ecsv
