Compatible with iOS 11, 12, 13 and 14

My Clock app was full of alarms because I'm the type of guy who needs several alarms to wake up.

I saw this post on reddit with many upvotes so I decided to do something about it.

Features:

• Create alarm groups and add existing alarms to it
• Generate a set of alarms with a given interval while creating the group
• Enabling/disabling an alarm group will enable/disable all the alarms inside it
