Implements file path expansion and normalization routines from MRI Ruby.

A new function (normalize or make_absolute or something, bikeshed away) should be added that will turn a relative path into an absolute path without touching the filesystem. (rust-lang/rust#59117).

This crate normalizes and absolutizes paths according to the logic in Ruby v3.0.2 for POSIX and Win32.

Add this to your Cargo.toml:

[dependencies]
ruby-file-expand-path = "0.1.0"

Then normalize paths like:

assert_eq!(
    ruby_file_expand_path::expand("/home/artichoke/scripts/../run.sh"),
    Ok(b"/home/artichoke/run.sh")
);
