Improve PCA post processing output message formatting.

Continued improvements to PCA; handle errors better, make number of
processing threads configurable, and reversed the "keep-orig" option to
"delete-orig" which makes more sense.

Converted PCA to be multithreaded and use libpackjpg instead of calling
the old packjpg executable. This works much better! Need to handle a few
error conditions and do some more testing with decompress.

Move includes to source file and add forward declarations in their place
so that the packjpg.h header can be used externally.

Fix library name and include path for install target.

Remove no-longer-supported MACs: hmac-ripemd160

Update upgrade_makemkv.sh to open the MakeMKV license webpage after
installing.

Adding generate_rows.py script.

Adjust parsing of mdadm output as apparently the format has changed slightly. Perhaps a more dynamic style of parsing should be used.

Add some debug to checker.py script.
