* fix clippy::unused_io_amount See related clippy documentation, but in short some partial reads can occur in particular with io on the networl. read_exact/write_all transparently handle such errors. The fix actually revealed a bug in 'mp4a' atom parsing, but this is a dangerous change: Parsing bugs that were transparently ignored are now failing with error (unattended io eof). * fix trivial clippy errors * fix clippy error with always 0 value * run ci/cd with clippy and latest rust version
