Enhance Bufr data support including multi-category messages in a sigle data file, so that prepbufr data file is supported. Also CMA bufr tables were added for reading CMA released bufr data files.
Description of Changes
_ Add CMA bufr tables (table B and D) as resource tables for reading the bufr data files released from CMA.
_ prepbufr data file may containes multiple category messages such as ADPUPA, ADPSFC, etc. BufrIosp2 only support single category messages before. So BufrIosp2 and related classes (BufrIospBuilder, EmbeddedTable, TableA, ...) was revised to support more root variables (not just 'obs').
_ 'reallyRead' function in ucar.nc2.Variable class has problem when a Structure variable read result is ArrayObject with ArraySequence as elements, so it was revised to solve the issue.
I test them using MeteoInfoLab (version 3.9.7) bufr reading scripts with netcdf library behand.
