From: Niklas Haas <g...@haasn.dev>
Switches to av_frame_remove_side_data_changed(), covering a number of
cases that we previously ignored. Additionally, stop stripping metadata
when merely changing colorspace or color range, since these do not
affect the actual color volume of the image data, only the encoding.
