WAV file parser fails with "Invalid Header Format" for some valid files

[sjmurdoch]

When using a file source for decoding, for some valid files QSSTV will fail with the error message "Invalid Header Format". This appears to be due to the decoder requiring that the first two chunks of the RIFF file are fmt and data. However, programs that create WAV files will often have chunks like INFO and auxi before the data chunk.

As a workaround, sox can be used to remove these chunks, e.g.

sox SOURCE.wav DESTINATION.wav

Do you have an example WAV file to reproduce?

Here's one, I think generated by SDR Angel

I have the same issue with WAV files produced by Audacity and receiving software on my phone.
