Feature: Allow switching presets using hotkey

Disclaimer:

• [x] I have checked for a similar issue and sure it hasn't been reported before.

Description: I would like to switch the current preset using a hotkey. As a rudimentary example to switch between 'Music-Mode' and 'Voice-Mode'. This could be implemented with [somekey] + [arrow up/down] to switch one up/ down or [somekey] + [1-9] to select a specific preset. Maybe display a toast/notification with the name of the newly selected preset.

User flow & interface: This could be configured using the settings menu. For switching up/down it would suffice to be able to change the hotkeys here. For switching to a specific preset an assignment to the numbers would be needed.

I've created a crude enable/disable function of eqMac by using Keyboard Maestro to open it, locate the on/off icon, detect whether on or off, and click if wanting to toggle it. This allows you to then apply a hotkey, run at specific time, or other arbitrary control via Keyboard Maestro.

Macros available here and are very generalized: https://github.com/samyk/samytools/tree/master/keyboardmaestro
