Add a LICENSE file

[kmturley]

Hello, Could you add a LICENSE file to signal your intention for reuse: https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/licensing-a-repository

Note that the LICENSE should cover the samples too. So make sure you know the license for those too.

This would be much appreciated, so no misunderstanding going on for licensing
