These provide the ability to integrate the SDK with some other application
loggers.

At the time this was written we use Timber on Android and CocoaLumberjack on iOS.

In addition to the integration capabilities, a LogBridge React Native module
provides log transports for JavaScript code, thus centralizing all logs on the
native loggers.

React Native doesn't define __filename nor __dirname so do it artisanally. In
addition, this helps with centralizing the configuration passed to loggers.
