From: Christopher Degawa <christopher.deg...@intel.com>
Equivalent to the --lp option for SvtAv1EncApp, and is the only way
to control how much cpu power svt-av1 uses for now
Not using thread_count as it would be preferable to reserve that until
svt-av1 properly implements a threads option
0 == getconf _NPROCESSORS_ONLN
