CallbackQueuing invalid syntax

[dmrossman]

This is my first time entering an issue on GitHub, so please excuse my lack of experience. I tried to use the secs.py code in the simple directory. On line 2362 I get an invalid syntax for CallbackQueuing(self._rpm_cb) as pmq. PyCharm is suggesting that CallbackQueuing doesn't specify the return value of the CallbackQueuing init method?

Thank for issue report.

Maybe, this work over version 3.9 currently.
I plan to fix. This repository assumes version 3.7.
I didn't know that 'with statement' use with '()' is work over version 3.9.

Thanks regards.
