The `globset::Glob` type [`new`] function creates a new value with an `&str` parameter which returns an `Result<Glob, Error>` object. This is exactly what [`std::str::FromStr::from_str`][`std::str::FromStr`] defines. Libraries like [`clap`] use [`std::str::FromStr`] to create objects from provided commandline arguments. This change makes this library usable without a newtype wrapper.
