Raw AAC may be broken in FFmpeg input

[kode54]

Describe Raw AAC input may be causing a division by zero exception due to either having a 0 channel count or 0 bits per sample. The latter would be impossible to trigger without there being a failure to open the file, so the former indicates that something is up with the channel layout detection. I'll have to deal with this a little later.

To Reproduce Steps to reproduce the behavior:

1. Add some raw ADTS AAC files
2. Crash on open of possibly mono or stereo file? Unknown.

Expected behavior Files should open without incident.

Version information:*

• macOS version: 13.4.1
• Cog version: 2783

Additional context This was a user submitted crash report. It occurs in the audio decode path due to division by zero error on Intel, not sure how that manifests on Apple Silicon.
