Added bounding box rect properties to outputted window results

[visgotti]

Needed this info and the only other npm module that I could find to get the rect was only getting the active window's data. Hopefully someone else might find this useful.

This could be useful for someone 👍.

I'm just wary about paying the cost to get the rects each time, even when the caller doesn't need the information.

Perhaps this addition could be in a separate npm module? It could export a function which takes the list of window handles from listOpenWindows() and gets their rects? I could link to such a module in the README on this module.

or just have it behind a flag -.- npm ecosystem is screwed up as it is at this point.
