Philippe 07/03/2024: move allocation/deallocation of variables used in NAM_BACKUP and NAM_OUTPUT in dedicated subroutines

Philippe 12/01/2024: allow more coupling files (up to 1000, can be increased with a parameter) + compress list

Philippe 10/01/2024: check that CSEG and CEXP do not contain . or space characters (replace them by _)

V.Masson 03/01/2024: optimization of NRAD_AGG options (now radiations is not called on already-called columns when using the aggregation)

Philippe 22/12/2023: IO: allow more flexible filenames (CEXP and CSEG are a lot bigger and are trimmed) + use NFILENAMELGTMAX for all files

Valery M. 08/12/2023: add new option NRAD_AGG to compute radiation only on an average column of size (NRAD_AGG^2 points).
It reduces by NRAD_AGG^2 the cost of the radiation calls but is not yet fully optimized when the number of inner domain by cores are lower than 20x20 columns

- new version of ELEC can be used with:
   - (ICE3, LRED=T)

   - (LIMA, LPTSPLIT=T)

- add charge exchange during CIBU and RDSF

- old version of ELEC still usable

 - new version of ELEC (ELE4) can be used with LIMA2
 - electricity-microphysics retroaction added in LIMA
 - limitation of microphysical options to be used with ELEC

Quentin 21/09/2023: PHYEX v0.6.3 impacts on MNH files (changes from PHYEX v0.4.1 which is mostly change from initialization of param

Philippe 20/04/2023: allocate and compute surface fields for flyers, aircrafts, balloons and DIAG only when useful

Philippe 10/02/2023: rename blaze namelist and modules for grid-nesting (not yet supported for blaze)

(cherry picked from commit d3a8aba96b64e6f16367d1c06c84d58f4f52bfb4)

Quentin 25/10/2021: bugfix RESTART reproductibility. In the case of no online chemistry (LORILAM=F) or LDUST/LSALT=T processes changing the aerosols (XAER)
at each time-step, XAER is computed once at the START segment in ini_ecmwf_radiations based on current pressure and not updated during MESONH except if LAERO_FT=T and CAER='TEGE'. At RESTART, the aerosols climatology is updated but the
pressure has changed. For reproductibility, one must use LAERO_FT=T and CAER='TEGE'. XAER_CLIM was not updated in the process done by CALL AEROZON in phys_param

F.Couvreux 30/06/2021: add LRELAX_UVMEAN_FRC forcing. Instead of LRELAX_UV_FRC which applies the u,v relaxation read in namelist on each atmospheric column,
LRELAX_UVMEAN_FRC applies the relaxation on the horizontal mean of u and v at each level. To be used in LES mode.
