point-in-polygon package is no longer maintained

Hi,

This package has a direct dependency on point-in-polygon, which appears to no longer be maintained:
https://www.npmjs.com/package/point-in-polygon
As shown by the NPM package page, it hasn't been published for 5 years and the link connects to a repository that no longer exists:
https://github.com/substack/point-in-polygon
This makes it impossible to determine copyright, unless resorting to this archived repository:
https://archive.softwareheritage.org/browse/origin/directory/?origin_url=https://github.com/substack/point-in-polygon&visit_type=git

Please could you consider not relying on this package any longer?
