Add Logging & Crash Reporting

[berenteb]

For our own comfort, we should implement some logging and crash reporting tool such as Firebase Crashlytics. This can also save logs that lead up to crashes or smoething. Should be investigated further.

Update: Most of the solutions on the market are paid, Firebase SDK with Crashlytics and Analytics require native code, therefore it cannot be used with Expo Go. This is a tradeoff that adds not much bit takes away too much , therefore it is a no go for now.
