UPDATE [huge]:
large update of the code which follows the thorough testing of all the ED-RDMFT drivers.
ED SOLVER updated with the latest version, featuring: cg_method to select different
CG-fit routines and routines to enforce the particle-hole  symmetry.

RDMFT code updated with routines to enforce left-right symmetry and particle-hole ones.
All symmetries have been imported and tested on each driver.
New setup of default variables following best results in testing.
New drivers for square lattice, slab and winding stripe for AHM and HM.

Hloc bug (hopefully) completely removed from the code.
ready for further tests on disorder and winding stripe of AHM.
