datatest-stable 0.2.1

Changed

• The test signature is now fn(&Utf8Path) rather than fn(&Path). If necessary, a Utf8Path can be converted to a &Path with .as_ref() or .as_std_path().
• Non-Unicode paths now consistently produce errors. Previously, the treatment of such paths was inconsistent -- they would either be skipped or produce errors.
• Internal dependency update: libtest-mimic updated to version 0.6.1.
• MSRV updated to Rust 1.60.
