implemented new module 'CoReg_local' for detection and correction of local shifts; revised some functions due to changes in external library 'py_tools_ds'

components.CoReg:
- imParamObj: updated derivation of nodata value and footprint polygo
- COREG: - added attribute 'deshift_results'

components.CoReg_local:
- added as new module for detection and correction of local shifts

components.DeShifter:
- moved DESHIFTER property '_dict_rspAlg_rsp_Int' to module top-level
- _get_out_extent(): updated algorithm

components. Geom_Quality_Grid.Geom_Quality_Grid:
- __init__():
    - changed most of the input args and kwargs
    - revised the whole function -> COREG_obj is not instanced within class COREG_LOCAL
    - added property 'CoRegPoints_table'
    - added property 'GCPList'
    - dump_CoRegPoints_table(): revision
    - quality_grid_to_PointShapefile(): refactored to 'to_PointShapefile'
    - _quality_grid_to_PointShapefile(): refactored to '_to_PointShapefile'
    - quality_grid_to_Raster_using_KrigingOLD(): revised getter for path_out
    - _Kriging_sp(): revised getter for path_out
    - view_results(): moved to class COREG_LOCAL
    - view_results_folium(): moved to class COREG_LOCAL
    - correct_shifts(): moved to class COREG_LOCAL

components.geometry:
- get_true_corner_mapXY(): adjusted some lines due to update of 'py_tools_ds'
- find_noDataVal(): moved to external library 'py_tools_ds'

__init__:
- updated __version__
