fst-bin: drop docopt in favor of clap

This was a grueling refactor, but it's done. We now correctly handle non-UTF-8 arguments in most places. We also switch to anyhow for error handling, so setting RUST_LIB_BACKTRACE when an error occurs will show something useful (assuming it was built with a nightly compiler).
