Not compatible with `android.enableBuildConfigAsBytecode` Gradle Property

**Problem:**
If the `android.enableBuildConfigAsBytecode=true` flag is set in the `gradle.properties` file, no secrets or extensions will be added to the `BuildConfig`.

The flag being enabled or disabled does not affect the ability of anything to compile or affect the standard `BuildConfig` flags. This package will only work if that feature is disabled.

This incompatibility is problematic because
1. it significantly affects compile-time
2. the [advice given here](https://medium.com/androiddevelopers/5-ways-to-prepare-your-app-build-for-android-studio-flamingo-release-da34616bb946) would cause this to fail and there aren't any logs or other indicators that this is the issue.
