Quentin 18/12/2023: modifs introduced to plug ELEC into PHYEX

- Add routines from mesonh electricity scheme needed within rain_ice and lima;
- Plugging into AROME and LMDZ
- ZTHVREFZIKB must be removed someday or computed correctly if really needed in elec;
- use of D and CST within elec routines
- cleaning modules uses within elec_tendencies
- convert elec routines in mode_
- TODO: ELECD and ELECP must be extended and used everywhere within elec routines

Christelle B. 24/10/2023: ELEC: avoid duplication of microphysics routines
- new version of ELEC can be used with:
   - (ICE3, LRED=T)

   - (LIMA, LPTSPLIT=T)

- add charge exchange during CIBU and RDSF

- old version of ELEC still usable

 - new version of ELEC (ELE4) can be used with LIMA2
 - electricity-microphysics retroaction added in LIMA
 - limitation of microphysical options to be used with ELEC
