Allow BUFR reader/writer to handle GRACE-FO profiles

[Ian Culverwell]

We should probably make arrangements for this satellite. An email from Harald Anlauf on 1/5/2018 suggests some codes:

Dear colleagues,

after discussing matters, DWD is preparing a proposal for the next IPET-CM meeting taking place in Offenbach at the end of May.
The current proposal is to assign the following codes:

Table C-5:

   Satellite-ID    Name
      802          GRACE-C (GRACE-FO)
      803          GRACE-D (GRACE-FO)

Alternative proposals would include GRACE-FO-A and GRACE-FO-B,
GRACE-F1 and GRACE-F2, or similar.  If nobody objects, I'd prefer to stay with the shortest variant above.

Table C-8: (Instrument ID)

   Code   Agency    Shortname     Longname
   104     NASA     Tri-G         Triple-G (GPS, Galileo, GLONASS)

The code (104) has been suggested by Doug and is still available.
The other information would make the entry also agree with the current OSCAR entry, except that I have shortened the shortname from "Tri-G (GRACE-FO)".

With BUFR messages, both satellite ID and instrument ID are provided.
If it is considered important, we will propose the longer version of the shortname to appear in the document

pages 33ff.

I'd appreciate your feedback - or rather approval :) - soon, so that the proposal will be ready in time for the meeting.

Thanks,
Harald

We could use these provisionally. Code and BUFR document would need updating.

After checking with Harald, these suggestions were amended:

Hi Ian,

attached you'll find the latest status of the proposal:

- the satellite IDs were shifted to 803 (GRACE-C) and 804 (GRACE-D)

- the instrument ID has not been challenged

The codes should appear in the next fast-track documents (later this year).

Regards,
Harald

These proposed GRACE FO codes were incorporated in the ic_gnos branch at r5553 and r5554. See #377 for results of testing.
