ad29f9e47c avcodec/tiff: Restrict tag order based on specification 
"The entries in an IFD must be sorted in ascending order by Tag. Note that this is
 not the order in which the fields are described in this document."

This way various dimensions, sample and bit sizes cannot be changed at
arbitrary times which reduces the potential for bugs.
The tag reading code also on various places assumes that numerically previous
tags have already been parsed, so this needs to be enforced one way or another.

If this commit causes problems with real world files which are not easy to fix
then some other form of checks are needed to ensure the various dependencies
in the tag reading are not violated.

98f7e0081b avcodec/cbs_av1: fix setting FrameWidth in frame_size_with_refs() 
Section 5.9.7 of the spec states

    UpscaledWidth = RefUpscaledWidth[ ref_frame_idx[ i ] ]
    FrameWidth    = UpscaledWidth
    FrameHeight   = RefFrameHeight[ ref_frame_idx[ i ] ]
    RenderWidth   = RefRenderWidth[ ref_frame_idx[ i ] ]
    RenderHeight  = RefRenderHeight[ ref_frame_idx[ i ] ]

Meaning FrameWidth must not be set to RefFrameWidth[ ref_frame_idx[ i ] ]
like we're currently doing.
