Highlights

• fcp now uses significantly less heap-allocated memory without sacrificing any speed (e.g. profiling of fcp copying the Linux source tree on macOS shows an 8x reduction in heap-allocated memory usage compared to v0.2.0).
• fcp now makes significantly fewer lstat/xstat syscalls while walking directories by taking advantage of the filetype information stored in each directory-entry.

Minor Improvements/Additions

• Previously fcp included all of its test fixtures in its .crate file uploaded to crates.io, bloating its size dramatically. These fixtures are now properly excluded, reducing the .crate file size from 726 KB to 17 KB.
• A binary is now available for aarch64-unknown-linux-gnu.
