titleDeleted parameters and changes to encoding of existing ones

In preparation for the Migration to Grib2, from Important announcements for version 2.28.0

Deletion of unused parameters

[ECC-1478, ECC-1480, ECC-1486, ECC-1499] Please note that the following parameters have been deleted in favour of updating parameter definitions which adhere more closely to WMO encodings. In each case, MARS has been investigated to ensure that the encoding has not been previously used to archive data. The deleted parameters are:

paramId

shortName

name

units

discipline

category

The parameters to use in place of these parameters are:

260003 --> 231
260258 --> 232
260083 --> 159
228033 --> 228217
260075 --> 3008
260179 --> 172
3102 --> 140234
3103 --> 140236

Modifications to existing parameter encodings
[ECC-1469] Please note that several parameters have had their encodings modified to better match WMO encodings, as well as to better match encodings that are used as standard practice to archive these parameters within MARS. In each case, this was confirmed by crawling the MARS archive. Please see [ECC-1469] for the affected parameters.

Modifications to existing parameter long names
[ECC-1470] Please note that several parameters have had their names changed to better match WMO names whilst also keeping the existing ECMWF naming scheme. This results in replacing "solar" with "short-wave (solar)" and "thermal" with "long-wave (thermal)" in several parameters. Please see [ECC-1470] for details.

Info

Addition of GRIB2 parameters and GRIB2 encodings

[ECC-1464, ECC-1465, ECC-1466, ECC-1479, ECC-1481] Please note that several new parameters have been added with GRIB2 only encodings, and several parameters have been updated with their correct GRIB2 encodings, which either replaces a previous discipline=192 encoding or is new entirely. Please see the related tickets for more information

there has been a number of changes in the way a number of parameters are encoded in GRIB 2. There are also a number of new parameters, some existing ones have seen their names changed, and a small number of them have been removed. Check the corresponding links for the details of the parameters affected. If ecCodes 2.28.0 or later is used to encode those parameters that changed encoding, it will not be possible to correctly decode them for earlier versions.
