[Cin]Nite about MXF sample rate limitations

As of ffmpeg 8.1.2 I see this if I try to encode video with 22khz audio into mxf container [mxf @ 0xb4000075eef6e230] only 48khz is implemented in red. Can you pretty please add comment line into each mxf profile saying "at least ffmpeg 8.1 only implement audio samplerate 48khz for mxf, be sure to set project's samplerate to 48000" Yeah, a bit wordy. But I bet we will forgot about this little detail otherwise ... Also, may be tweak avcintra-100 mxf profile comment AGAIN noting that yeah, you can delete b=100m line but result will be not spec-compliant, better tweak mxf_h264_b profile instead?
