CRA-505, CRA-727: Changed high-cut-seismic-resolution in xmlmodelfile from setHighCut to setMaxHzSeismic. Added doFiltering (and vp seismic logs) well writing is requested.
CRA-505, CRA-727: Added doFiltering (and vp seismic logs) if filter-elastic-logs is true. Set filter-elastic-logs to be false by default. Combined options of setting up spat_synt_well_filter in avoinversion so doFiltering works if prior corr isnt estimated.
