vf_tonemap: Update hdr metadata with the new peak value
...
Less effective than the approach in vf_tonemap_opencl because there
is no peak detection, but it's still a good idea to implement this.

vf_tonemap: Fix logic for detecting the maximum peak of untagged sources
...
When there is no metadata attached to a frame, take into account both
the PQ and HLG transfers, and change the HLG default value to 10:
the value of 12 is the maximum range in scene referred light, but
the reference OOTF maps this from 0 to 1000 cd/m² on the ideal HLG
monitor.
This matches what vf_tonemap_opencl does.
