[FEATURE] Add hvc1 tag to HEVC MP4 conversions

Request Type:
NEW FEATURE

I find that Apple products will play the files converted to HEVC MP4 will play if -tag:v hvc1 is in the ffmpeg-video conf. This is what I use and I find that it performs better.

-ss 0 -tag:v hvc1 -vf yadif=0:-1:1,hqdn3d -vcodec libx265 -preset medium -crf 26 -map 0:v -sn

This feature has been added in todays 2.5.7 beta build

The stock profiles will create hvc1 compliant hevc videos for both handbrake and ffmpeg

Awesome! Thank you
