android builds (#9)

This adds android builds to the CI infrastructure. These builds generate an `apk` file that you can download and install.
- Adds a new container build job that builds a container with all the required android dependencies
- Adds a new release build that builds an android apk
- Updated the imp module to split out mobile and desktop behavior
- Adds logic to request microphone permissions
- Added a custom android manifest that declares the required permissions
