UCS-2 handling for Rust.

Note that UCS-2 is the predecessor of UTF-16. It is a fixed-length encoding, and it is used for things like UEFI.

This crate arose out of the needs of the uefi-rs crate. The code was extracted and placed here for easier maintenance and easier reuse.

Most of the initial code has been contributed by FredrikAleksander.
