Add BUFR support for TerraSAR-X

[Dave Offiler]

1) emails with Jens Wickert (GFZ) regarding recent launch of TerraSAR-X and potential availability of RO data from it

2) emails with Stan Kellet (MetDB) about formally obtaining WMO BUFR codes for satellite and instrument IDs for IGOR on TerraSAR-X

Jens,

I didn't expect any data to be available to users in the first 6-months
(at least). Just establishing the principle so we can plan for it.

Ok, I'll make the next release of ROPP recognise "TSRX" in the ROPP
files, where "CHMP" and "GRAA" occur in current files. 

We'll also have to establish a code for the WMO BUFR tables, too. If
TerraSAR-X is a German satellite, like CHAMP, then it would be logical
to assign code 42 (CHAMP is 41 - 001-070 being for European satellites).
(GRACE-A/B are classed as US satellites, and are 722/723).

Ok, I will prepare anofficial document for the ETDRC team to approve.

OK, I'm happy with 42 + 103. On the assumption these will be accepted, I
will add them to my local table versions. No TerraSAR-X raw RO data is
expected before October, and the processed data probably won't be on GTS
this year.

[Dave Offiler]

Look-up tables in ropp2bufr.nl and default in-built tables in ropp2bufr.f90 and bufr2ropp.f90 updated to include support for TerraSAR-X assuming proposed codes are "TSRX" (for ROPP files) and 42 + 103 for BUFR satellite & instrument codes, repectively. Committed as [1180].

Local version of BUFR file CODEFIG has also been updated to support TerraSAR-X; tested in bufr/extra/ using test_tables tool & copied to working BUFR_LIBRARY. Updated BUFR package (MetO BUFR release v16.6 21/6/2007)

Closing ticket, but may have to be re-visited if proposed codes are changed prior to acceptance by WMO.
