First, thanks for writing this awesome crate.

But it looks like the author is busy. The last commit was about seven years ago. And some PRs hanging for years.

I made some improvements based on this project.

See https://github.com/hack-ink/unescaper.

I found this package while looking for a package that takes a Rust string and spits out an escaped JS string. Being able to go back/forth (or in my case the opposite direction) would be very helpful

unescape(r#"\r\y\n"#) returns None but does not tell us where the problem is (either position or range).

This could be used in the solang compiler so that it can return the exact position for an error.

I am currently trying to use this crate to unescape some javascript strings, however the following examples are failing to unescape.

In the above table, the first cell represents a valid js string with escape sequences. The next column represents how that would be represented as a &str in Rust. The third column is the anticipated output, however the unescape function this crate exports returns None for both examples.
