Added functionality to launch a Loom App via a custom URL scheme for Android and iOS apps (scheme+host isn't analogous across Android and iOS, so we support 'scheme' only).  The scheme to use is set in the AndroidManifest.xml (Android) and Info.plist (iOS) manually, and will require a soon to be updated LoomCLI for automated overwriting from the app's Loom.config.

This also includes support for data query keys passed in with the custom url for the application to request and use, ie. 'playLoom://?someKey=someData&someKey2=MoreData'.
Helper function to pull <meta-data> from the AndroidManifest
