Enable Mouse.scrolled events for macbook touchpad

[aspauldingcode]

Problem: Sketchybar allows to subscribe to mouse.scrolled() events, which allows me to use scroll for volume_change.

However, it only works on my mouse. If I use my macbook air m1 touchpad, the two-finger scroll doesn't activate the mouse.scrolled() event in sketchybar, meaning I cannot use scroll to volume change on the go.

Solution: allow two-finger scroll to activate mouse.scrolled() event
