Gsub: A CLI tool for string substitutions in a directory

This tool presents itself as a much faster and ergonomic alternative to shell pipelines with sed.

e.g.

    rg foo --files-with-matches | xargs sed -i 's/foo/bar/g'

becomes

   gsub "foo" "bar"

And runs significantly faster.

I don't know if I'll install it, but it's an interesting concept.
