aa8e5eecac 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.

e467179cfb vf_tonemap[_opencl]: Move determine_signal_peak() to a shared file 
The two functions are identical. Use the shared LumaCoeffients type too.

ce7ca726b2 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.
