Hard-coded value here and below, this test already has lots of these.

Also adding this new asset, not strictly needed for this PR, but still useful to check a format that's not fltp.
It will be needed in #556 anyway. It's from TorchAudio.

Towards #549
This PR adds the
sample_formatfield toAudioStreamMetadata. In terms of values, it'll be whatav_get_sample_fmt_name()returns, so it's a bit "ffmpeg-like": flt, fltp, s16, s32... Maybe we'll want to expose a more user-friendly string? I'm not sure, either way, we can always re-map as follow-ups.
