Update utilities.py (#542)

Browse Source 
Updated the extraction process with the ffmpeg command that corrects the colorspace while extracting to png, and corrected the ffmpeg command, adding '-pix_fmt', 'rgb24', '-sws_flags', '+accurate_rnd+full_chroma_int', '-colorspace', '1', '-color_primaries', '1', '-color_trc', '1'

'-pix_fmt rgb24', means treat the image as RGB (or RGBA)
'-sws_flags +accurate_rnd+full_chroma_int', means use full color and chroma subsampling instead of 4:2:0
'-colorspace 1', '-color_primaries 1', '-color_trc 1' put the metadata color tags to the png
