"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.

mpegts_read_header stops parsing the file at the first PMT. However the check
that ensured this was wrong because streams can also be added before the first
PMT is received (e.g. EIT).
So let's make sure we are in the header reading phase by checking if ts->pkt is
unset instead of checking if the number of streams found so far is 0.

Version 1.1 (FX Fighter) files all have a sample rate of 44100
in the header, but only play back correctly at 22050.
Force the sample rate to 22050 when reading, and restrict it

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.
