Description

Add a new method in the debugger (setDebuggerAvailable) that allows a developer to override the default setting that makes the debugger unavailable in production builds

Motivation and Context

There are some scenarios where a developer could want to have the debugger enabled in a production build, or change this behaviour at runtime (for instance, have it enabled in an integration environment but disabled in production one).

Fixes: https://github.com/marvelapp/react-ab-test/issues/3, https://github.com/pushtell/react-ab-test/issues/49
