CLI: Implements custom anamorphic. No more -p or -P. Choices are --strict-anamorphic, --loose-anamorphic, and the new --custom-anamorphic. The last of which also handles --pixel-aspect, --display-width, --itu-par, --modulus, and --keep-display-aspect options. Loose will also obey the pixel aspect and ITU PAR options.

Libhb: Fixed a small bug with custom anamorphic working off the source's display aspect even when dealing with a custom display aspect, and made the job config display aware that custom anamorphic exists.

Scripts: Updated manicure to write the new anamorphic option names.
