Notification grouping

Hi there,

I wish to suggest a new feature: Notification Grouping on the Android app.

By this, I mean that when more than one Numberbarn notification appears in the notification drawer, I would like it to appear in a collapsible list under a single Numberbarn notification. Currently, the only options are to display all of the notifications individually, which clutters the notification drawer, or turn them off altogether, which would result in missing incoming messages.

There is also currently a separate Numberbarn icon displayed at the top of the screen for each notification. I assume that implementing the feature would also resolve that and display a single numberbarn icon at the top of the screen, no matter how many messages are waiting.

Thank you for your consideration. Otherwise I really enjoy the app and the service!
