Mars GCM:
Implementation of the IRabs-to-VISext dust scenario conversion, depending on the GCM effective radius :

• new flag 'reff_driven_IRtoVIS_scenario', false by default, must be set to true to use this dynamic conversion (otherwise, the coefficient takes the constant value of 2.6, eqv to reff=1.5um, as before) A specific line is added in deftank/callphys.def.GCM6
• this flag requires the 'dustiropacity' to be set to 'tes' to match the IR scenario's wavelength. 'mcs'-like dso diagnostics can only be produced by the use of the post-processing tool util/aeroptical.F90
• the variable IRtoVIScoef is computed in aeropacity via the GCM CDOD ratio : tau_pref_gcm_VIS/tau_pref_gcm_IR (only at the first call to callradite during each physical timestep)
• change read_dust_scenario into module read_dust_scenario_mod
