Subject: [PATCH] feat(notif): Swipe to delete notifs on map screen

Add swipe to delete functionality to reminder cards displayed on the maps screen. Users can swipe left on any reminder to delete it. Still needs to be changed to round edges for the UI.

Change was added as there was no easy way to delete reminders prior to this.
