Philippe 07/01/2021: IO: remove GCLOSE_OUT variable/dummy argument (lopened field of tpfile datatype can be used instead)

This is incomplete for the moment. MesoNH must always be compiled with this key for the time being.

(cherry picked from commit fcebfc18)

Philippe 15/12/2020: menu_diachro: more intelligent ygroup allocation (waste less memory + no more risk of access out of range)

Philippe 08/12/2020: budgets: modify group_name management (in order to merge different times in further commits for netCDF files)

Philippe 07/12/2020: add CLEANLIST1D_ll subroutine + use it to correctly deallocate associated memory

Philippe 24/11/2020: rename NMNHDIM_BUDGET_MASK_TIME -> NMNHDIM_BUDGET_TIME and time_mask -> time_budget

Philippe 13/11/2020: IO: improve CF compliance (add missing unit, does not write empty standard_name)

Quentin 28/10/2020: default value of LRED is now TRUE (LRES = reduction of time dependency of ICE3/ICE4 microphysics scheme)
