README: Add author field
.functions: Add `targz`

`targz some-directory` creates `some-directory.tar.gz`, where compression is handled by either `zopfli` (if available) or `gzip`.
.functions: Avoid `rm` error message in `targz` when `gzip` is used
.functions: Improve `targz`

* Only use `zopfli` when it’s available and if the `.tar` file is smaller than 50 MB.
* Use `pigz` instead of `gzip` when it’s available.
* Always exclude `.DS_Store` files when creating a tarball.
