If a level 10 codestream is required, JxlEncoderSetBasicInfo
will fail as it verifies the codestream level restrictions.
However, there's no way for the library to provide the info
on what codestream level is actually required until the BasicInfo
struct is already set. Thus, we work around this pro

Add pat and pmt table at start of each segment in single_file mode enhanced
compatibility of hls stream. Because some hls clients separate parsing segment
of hls stream, the absence of pat/pmt will cause parsing to fail.

So I make it error to handle.

The previous code expected a segment of type CLUT definition to exist
in order to accept a set of segments to be complete.
This was an incorrect assumption as the presence of a CLUT segment
is not mandatory.

to call ff_request_frame with the correct input pad
