Bugfix for deadlock in multiprocessing in case matching window size greater...

Bugfix for deadlock in multiprocessing in case matching window size greater than 2x grid_res. Bugfix for wrong image grid equalization in case reference image has a lower resolution than target image.

- equalize_pixGrids(): bugfix for not respecting which pixel grid is to be used for coregistration

- get_CoRegPoints_table(): updated array caching calls

- updated __version__
