Merge changes from kh4 branch into main

[iamdonovan]

This PR would update the main branch with the following changes from the kh4 branch:

• change dependency to scikit-image >= 0.19
• add resample_hexagon command line tool, which replaces using mm3d ReSampFid for resampling KH-9 MC images

image module:

• add functions to find, match "wagon wheel" fiducial marks (ocm_show_wagon_wheels)
• re-factor, improve reseau field matching using new find_crosses and match_reseau_grid functions
• change join_hexagon to be able to handle KH-9 PC images
• add resample_hex, which uses gdal.Warp to resample KH-9 MC images based on the reseau grid

micmac module:

• update init_autocal to be able to specify camera name, focal length, frame size

tools module:

• find_reseau_grid now uses multiprocessing to run on multiple images, rather than on a single image
• join_hexagon changes to match image.join_hexagon
• resample_hexagon is now included as a command line tool
