This reverts commit 566b9f7e.

Execution time is now equivalent with or without array-syntax / do loops conversion

mesonh/micro/rain_ice.f90 -> mesonh/micro/rain_ice_old.f90
mesonh/micro/rain_ice_red.f90 -> mesonh/micro/rain_ice.f90
bugfix for the new condensation interface
interface harmonisation betwwen mesonh/micro/rain_ice_red.f90 and arome/micro/rain_ice.F90

Quentin 13/04/2022: bugfix infinite loop sedimentation init inner values of ZREMAINT (bug in mesonh only)

- lines too long
- missing & in ifdef REPRO48
- remove ,& in pointer association
- change of ASSOCIATE subroutine

Original code contained a bug (autoconversion ri->rs was not set
to 0 if ldsoft when ri content gets lower than the threshold).
Introducing REPRO48 in ice4_slow allows to suppress the one
introduced in compute_pdf to compensate.

CTURB_ASSOCIATE added
Character array delarations in turb

Simpler array declaration
ITPL initialisation
Cp computed using rain
