Request to cherry pick changes in dot release.

[spacecams]

Hello, thank you for taking the time to cherry pick changes for 3.5.0 release. If possible, would you be interested in taking https://github.com/ruuda/hound/pull/58 as well? I didn't see a branch on GitHub corresponding to the released version on https://crates.io/crates/hound, but I have patched the changes and uploaded them to https://github.com/spacecams/hound/tree/release-with-safe-changes. I ran the append and decode_full fuzzers and did not see any crashes. Let me know if I can make any changes or updates that would be helpful. Thanks!
