Replace affine6p transformation with numpy solution

[chkim-usgs]

Addresses https://github.com/DOI-USGS/ale/issues/573

The numpy solution is from https://stackoverflow.com/a/20555267.

Both the numpy solution and affine6p solution uses the least squares method (repo link for affine6p here).

This file affine_differences.txt shows the pytest difference output between the affine6p and numpy transformation estimations, respectively. The numpy output is fairly accurate to around the 10th decimal in comparison to the existing affine6p output in the test_naif_keywords() test.

Updated the test_lo_drivers.py to assert the TRANSX, TRANSY, ITRANSS, and ITRANSL values are almost equal to the affine6p output.
