Philippe 03/05/2024: Z-split files: manage correctly fields with 3rd dimension NMNHDIM_NLWB or NMNHDIM_NSWB

Philippe 17/04/2024: outputs: do not write dimensions and coordinates of main domain if it is not written

Philippe 17/04/2024: output: boxes: rename the dimensions to be similar to the main domain ones (allowed by CF conventions)

Philippe 11/04/2024: IO_Field_write_box_byfield_X4: added optional dummy argument to select a vertical subsection

Philippe 11/04/2024: Fill_tfieldmetadata: populate ndimlist if CDIR=XY for 4D fields (4th dimension set to NMNHDIM_NOTLISTED)

Philippe 11/04/2024: IO_Field_write_box: add IO_Field_write_box_byfield_N2 and IO_Field_write_box_byfield_N3 subroutines

Philippe 10/04/2024: outputs: add LOUT_PHYSICAL_SIMPLIFIED in NAM_OUTPUT to allow to write all fields with the same number of points even if not on same Arakawa grid position

Quentin + Philippe 05/04/2024: write XMUT only if program=MESONH + set it to 0. by default if not found at reading (and remove warning if not found)

Philippe 29/03/2024: outputs: remove non physical horizontal levels by default (possible to write them if needed)

Philippe 28/03/2024: outputs: remove non physical vertical levels by default (possible to write them if needed)

Philippe 28/03/2024: outputs: remove levels above Top Absorbing Layer earlier (possible after previous merge) + manage it correctly for the main domain

Philippe 27/03/2024: add the possibility to remove the Top Absorbing Layer from the boxes in output files

Philippe 27/03/2024: minor: use NMNHDIM_BOX_FIRST_ENTRY and NMNHDIM_BOX_LAST_ENTRY (instead of NMNHDIM_BOX_NI and NMNHDIM_BOX_LEVEL_W) for limits
