fix: always process all events in the queue on x11. (#73)

* Always process all events in the queue on x11.

Previously, there was always a 50ms delay between processing individual
events, which could lead to a queue of events building up if the key
repeat was higher than 20 Hz. This resulted in the global hotkey release
only being detected long after the key is released.
