Make initial commit of dependency license metadata

The `.licenses` folder contains a cache of license metadata for all the project's Go dependencies. This serves two purposes:

- Allow the Licensed dependency license checker tool to only check licenses when a dependency is added or updated
- Allow the maintainer to manually define license metadata when the licensee tool is unable to automatically detect it
