Philippe 19/11/2021: fix: correct lateral boundaries fieldnames for LIMA variables (be careful: forward compatibility with files is lost)

Philippe 19/11/2021: change MASDEV version to 5.5.1 (necessary due to change in fileformat in next commit)

Juan, Quentin 26/10/2021 bugfix RESTART reproductibility : use real(kind=4) for computation of LB and LS fields + DRYMASS sources bugfix

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

Quentin 04/10/2021: bugfix of the previous commit. The diagnostic surfex variables were not written at any first output file for every segment (instead of not written at time = 0s i.e. KTCOUNT=1 )

Quentin 30/09/2021: bugfix RESTART reproductibility. The surfex online diagnostics (but included pseudo-pronostic variables such as TSRAD) are written at
a time step of +1 in advance with respect to the atmospheric variables which lead to wrong computation of fluxes (such as radiative) at the initial step of a RESTART

Philippe 20/07/2021: modify DATETIME_TIME2REFERENCE and DATETIME_DISTANCE to allow correct computation with 32-bit floats

Quentin 19/07/2021: minor cosmetic change and modify HCAMSFILETYPE default value to NETCDF (only possible value for now)

Quentin 16/07/2021: stations : move LDIAG_RESULTS to LDIAG_SURFRAD and apply it (developpement was missing on station and write_station)

Quentin 16/07/2021: station change default time step to 60s and remove TYPE variable of csv reading.
TODO: remove the STATION%TYPE which is not used

Quentin 12/07/2021: bugfix revert from commit fde83373 for initialization of IPROC number of variable to write
