to be modified by Alessandro

used mex path to get ids_gen so has int32 and '' for empty strings

tested full chain for complete Corsica IDS and saveing to database through save/load quit matlab, awaiting for creat_imas bug to be resolved

tests explained in meq branch iter_dev README... file

Also fixes when MATLAB linter was complaining.

add trialindx when non empty for generic calls, to tcv2ids and fix legend in TCV/CXRS_get_profiles.m

integers should be piece-wise constant interpolated, and psitbxtcv2/psitbxtcv use unique(t) once closest times are taken, thus it removes time points if time_out array delta_t smaller than liuqe (which is easy since typically 17ms). At this stage modified psitbxtcv2/psitbxtcv with unique_t=false input arg in my matlab_imas folder

for ids as well, at this stage dealt with before output of gdat_tcv for each case with single function gdat2time_out.m
