The rain fraction diagnostic must be computed before calling ice4_tendencies in order to suppress all the 3D arrays in ice4_tendencies.
This modification will induce an approximation that should be acceptable.

Bit-reproducibility is broken when the rain fraction is used (small_3D_alt3 for AROME and ARMLES for Méso-NH).

In a test done with AROME with
CSUBG_AUCV_RC='ADJU',
CSUBG_AUCV_RI='ADJU',
CSUBG_RR_EVAP='PRFR',
CSUBG_RC_RR_ACCR='PRFR',
we can see (impact_RAINFR.pdf) a significant change in the rain fraction but no impact on rain intensity at ground (not shown).
