Use macOS API directly to detect input (instead of PyUserInput)

Since I'm now in possession of a Mac, I can actually do this.

We'd simply create a new file macos.py containing the necessary and remove the support for it in unix.py.

Especially important due to this problem.

Turns out it was as easy as:

from Quartz.CoreGraphics import (CGEventSourceSecondsSinceLastEventType,
                                 kCGEventSourceStateHIDSystemState,
                                 kCGAnyInputEventType)
seconds_since_input = CGEventSourceSecondsSinceLastEventType(kCGEventSourceStateHIDSystemState, kCGAnyInputEventType)
