Bugfix #2782 main_v11.1 MASSDEN (#2784)

* Per #2782, update the multiple matching records warning message to include the table number for each record. * Per #2782, update read_grib2_record_list() to parse the level values and aerosol information correctly for table 4.48. * Per #2782 tweak variable naming convention.
