Shuffle melodies

Describe the solution you'd like
Shuffle the melodies of selected alarms( the option should be added in #186 )

With an option to only shuffle using custom melodies

If we were to add an option where we can choose an option for 'Randomize' or 'Shuffle' when selecting melody for an alarm, would integrating this with #186 still be needed?

[mizu-048]

#186 would allow us to randomize multiple alarms at once

my initial idea was to have the melodies be shuffled among the selected alarms so only specific alarms are used
