Using intents for reader mode doesn't work well for 2 reasons: 1) Intents are used to resolve, but in reader mode we already know where to resolve to. Additionally, dispatching an intent causes additional latency. 2) Using intents with foreground dispatch was tricky; for every call to onNewIntent() with a new tag, there was a call to onPause(), which effectively disabled reader mode again, causing a discovery loop. Instead, let the app register a callback, and call that when we discover a new tag. Also, add new flag to disable platform sounds, and to change the presence check delay.
