Add recipe for libignition-utils1

[traversaro]

Fix #13551 . This adds the Ignition Utils library, the last maintained Ignition library that is missing from conda-forge. This includes the change proposed upstream in gazebosim/gz-utils#19 to avoid vendoring cli11 .

Hi! This is the friendly automated conda-forge-linting service.

I was trying to look for recipes to lint for you, but couldn't find any.
Please ping the 'conda-forge/core' team (using the @ notation in a comment) if you believe this is a bug.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipes/libignition-utils1) and found it was in an excellent condition.

This should unblock conda-forge/libignition-common-feedstock#29 and several other update PRs for other Ignition Libraries.

awesome. Just a little side-note: cli11 has unfortunately not seen a release in a while. not sure if the latest release is vendored or some more recent version branched off of "master"... (we're actually vendoring cli11 from master in micromamba because it has some improvements that we wanted).

I checked, cli11 1.9.1 is vendored in ignition-utils : https://github.com/ignitionrobotics/ign-utils/blob/main/cli/README.md .
