Add the option to also switch Default Communication Device when "Switch sound output to headphones" is enabled #434

Some apps like Discord only select the Default Communication Device specifically for "Default" Input/Output Devices. When MagicPods switches only the Default Device to my newly connected earbuds using the "Switch sound output to headphones" feature, Discord's "Default" Input/Output Devices still select whatever was set as the Default Communication Device last (which often is a different device) instead of the newly set Default Device, so I'd like for the option for both to be switched simultaneously.
