Add Crashlytics opt in option #82

[michaeltroger]

Add the option to enable/disable Crashlytics on demand.
This is commonly needed for high privacy standards. It allows you to start data collection only after the user explicitly opted-in. And you could offer the user a setting to disable the collection again in their settings.

Public API addition lacks KDoc. Please document behavior (default state, when it must be called relative to initialization, effect on pending crash reports) and link to Firebase docs to guide consumers.

	/**
	* Enables or disables automatic collection of crash reports.
	*
	* By default, crash report collection is enabled. Call this method to disable or enable
	* collection at runtime. This method should be called as early as possible, before any
	* crash events occur, ideally during app initialization.
	*
	* Disabling collection will prevent new crash reports from being sent to Firebase.
	* Pending crash reports that have not yet been sent will remain on the device until
	* collection is re-enabled.
	*
	* For more information, see the Firebase documentation:
	* https://firebase.google.com/docs/crashlytics/disable-crash-reporting
	*
	* @param enabled true to enable crash report collection, false to disable.
