tag: Adds basic exif tags support
Adds exif helper lib functions to parse exif buffers from/to
taglists. Exif is tipically used in jpeg images, but it can
also be embedded into TIFF, AVI and WAV formats.
Adds a couple function to handle exif in tiff header structures, that is how
exif is embedded in jpeg and (obviously) in tiff.
API: gst_tag_list_to_exif_buffer
API: gst_tag_list_to_exif_buffer_with_tiff_header
API: gst_tag_list_from_exif_buffer
API: gst_tag_list_from_exif_buffer_with_tiff_header
Fixes #614872
