Request for ANDURIL extension prefix

I'd like to request the prefix `ANDURIL` for [Anduril Industries, Inc.](https://www.anduril.com/)

Thanks!

Review the glTF extension-prefix registration process and existing prefix entries before determining how the ANDURIL request should be recorded. Done means the prefix request has been handled according to the project's established registration process and the resulting entry is verifiable.
