matcher 1.0 (new formula)

Resubmitting https://github.com/Homebrew/homebrew/pull/35012 with the fix:

>Matcher is a simple and efficient binary that implements TextMate's fuzzy path
> matching algorithm. It can be used in the CLI but is most often integrated with
> text editors like Vim to offer more efficient fuzzy file finding.


Make just use backticks and `assert_match` instead of `Open3`?
