Regular IOs don't toggle when plugin "Smart-Filament-Sensor" is enabled

[asoretmadolell]

Describe the bug
Regular IOs don't toggle when plugin "Octoprint-Smart-Filament-Sensor" is enabled, however the output test script does work.

To Reproduce
Steps to reproduce the behavior:

1. Create a "Regular IO" output type, IO number 15, and hook up an LED to it.
2. Test that toggling the output turns the LED on and off.
3. Install plugin "Octoprint-Smart-Filament-Sensor" https://plugins.octoprint.org/plugins/smartfilamentsensor/
4. Test toggling the LED again and now it doesn't work, however using the output test script it does work.
5. Disable plugin "Octoprint-Smart-Filament-Sensor".
6. Toggling the LED on and off now works again.

Expected behavior
Being able to use existing working configuration of "OctoPrint-Enclosure" with the plugin "Octoprint-Smart-Filament-Sensor" enabled.

Additional context
Hello! I know that very recently you have marked the plugin as deprecated after lots of debate. I think it's still a great plugin with the features it already has! However I think I have found a bug. I have read the troubleshooting guide thoroughly, so much so that I even solved an issue myself that I was already having with my DHT sensor (you will notice from the log file).

Like I said, when enabling the plugin "Octoprint-Smart-Filament-Sensor", something happens. Let me point you to the timestamp in the log file for the following actions:

• Until 2022-02-27 18:28:37,050 - All is working fine (except for the DHT sensor, though it was solved earlier in the afternoon) and the Smart Filament Sensor plugin is enabled
• 2022-02-27 18:31:13,611 - LED lights are toggled, exception is thrown
• 2022-02-27 18:31:46,299 - LED lights are toggled once more, with the same result
• 2022-02-27 18:33:20,496 - Smart Filametn Sensor plugin is disabled
• After that, LEDs toggle perfectly (ignore DHT errors)

Funny thing is that the output test script works perfectly. Therefore, I thought that it could have something to do perhaps with the toggle switch in the navbar. Just in case, here is a screenshot of the Smart Filament Sensor plugin ENABLED:

And here is one with the Smart Filament Sensor DISABLED:

There doesn't seem to be much of a difference, but at this point I didn't know where else to look.
What's even more funny is that the Smart Filament Sensor works perfectly, using different pins, and pausing the printer correctly when there is a filament runout.
I'll be more than happy to take your guidelines and help you test a bit further.
Enjoy your coffee! Thank you for everything!

Have you looked up about modifying GPIO cleanup command in Smart Filament Sensor source code? It fixed the issue for me with another plug-in.
