libhb: Clock/frame rate handling improvements.
Allows for arbitrary frame rates between 1 and 1000 fps.
Adds min/max frame rates to CLI help.
Removes hardcoded instances of the internal clock rate in favor of hb_video_framerate_get_limits().
Unfortunately, much of the codebase generally refers to clock rate as frame rate, so a little extra care is still necessary going forward.
