Added/Changed
* Lower level functions (EG: `windows.VCP.get_brightness`) now only support specifying the display as an `int`
* Low level `set_brightness` functions (EG: `windows.VCP.set_brightness`) no longer return anything
* Improved error traceback formatting. When using `verbose_error` the entire exception traceback is now included
* Added `start` kwarg to `windows.VCP.iter_physical_monitors`
* Sped up `windows.get_display_info` by reducing the number of calls to `wmi` APIs
* Moved `linux._EDID` to top level `EDID` class
* Changed order in which functions/classes are defined. Most relevant ones are at top of the file
* Added basic testing
* `linux.XRandr.get_display_info` no longer includes brightness in returned info by default
