Add utility to `rr.components.Color` to generate colors from any string (and use it in the air traffic data example) #11394

	# Jobs that only run for external contributors.
	# These have to be carefully sanitized, we don't want to leak secrets.
	# - We can't use caching, outside of really rare scenarios, because our caching largely depends on GCS
	# - We have to ensure that these jobs _only_ run for PRs outside of the `rerun-io` organization
	# this is done using the following check, added to every job:
	# if: github.event.pull_request.head.repo.owner.login != 'rerun-io'
