Use async/await #3
Description
It would be nice if asyncio and the new async/await features of Python could be used. Still the work should not be done in the main thread but a background thread (because parce needs to be usable for GUI applications that have the GUI in the main thread), and signals or events could still be used when a job is done. But it would be nice if that was handled by awaitables. Interaction with parceqt and/or other GUIs is important.
This thread is created to collect (my own or others) thinking about this subject and determine a way to go.
