Closes #11

Hi! Thanks for this great library! Like I mentioned in the issue, we would love to upgrade to a later version, but this is blocking us, so I thought I would implement it in a PR. It contains exactly the change in the issue.

uutils and eza are both using uutils-term-grid now, an actively maintained fork of this library. Many thanks to @ogham for creating an awesome library we can build upon!
