Sketchybar-py

* Adds native ARM Support
* Adds a querying api
* Refactored the bar item logic
* Optimized bounding rect calculation
* Shifts SketchyBar down if the default bar would occlude it

A very simple fix for item aliases.

* This fixes a scaling bug with item aliases occurring on retina screen.
* Adds y_offset property to items

* It is now possible to display default menu bar items in sketchybar (see Experimental section of the README)
* Improved Bar hiding responsiveness
* Bars can be hidden on individual displays
* Sharper text rendering
* Internal restructuring to reduce draw calls
* Rename domain *config* to domain *bar*

* Item backgrounds can now be customized with a border, a corner radius and a custom height
* New scripting variables for the space component include the display id and the space id of the associated component
* Fixes a bug where components of displays that are not connected are refreshed
* Some under the hood changes for (hopefully) better performance and stability

It is now possible to specify a border for the bar, e.g. a small 1px wide black border:
bash
sketchybar -m batch --config border_width=1 \
border_color=0xff000000
