CancelledError not handled properly

[mkiesel]

asyncio.exceptions.CancelledError should get handled properly (i.e., get raised to the calling code).
At the moment, e.g.,

pytonlib/pytonlib/tonlibjson.py

Lines 206 to 213 in 75d2fbf

	try:
	result = await asyncio.wait_for(self.loop.run_in_executor(None, receive_func), timeout=timeout + delta)
	except asyncio.TimeoutError:
	logger.critical(f"Tonlib #{self.ls_index:03d} stuck (timeout error)")
	self._state = "stuck"
	except:
	logger.critical(f"Tonlib #{self.ls_index:03d} crashed: {traceback.format_exc()}")
	self._state = "crashed"

marks the worker as "crashed" instead, which makes it difficult for outside code to stop gracefully.
