Another panic on malformed input

[Shnatsel]

When given a malformed input lewton panics with the following error:

thread 'main' panicked at 'index out of bounds: the len is 256 but the index is 256', src/audio.rs:558:13

Testcase: minimized_panic2_testcase.gz (gzipped so that github would accept the upload)

Command to reproduce the crash:
RUSTFLAGS='--cfg=fuzzing' cargo run --release --example perf /path/to/testcase

Tested on git commit ddd2408. Found using afl.rs

@Shnatsel btw, which are the license terms of the samples that were, will and are being submitted by you in the bug reports? Is cc0 okay?

Yeah, they're autogenerated by a tool I'm using, so I'm the copyright holder. I hereby release them under Creative Commons Zero 1.0.

@Shnatsel thanks!

Hmmm turns out the file was actually valid, not malformed. But the panic is a bug nontheless.
