Add support for Wemo CrockPot Slow Cooker

Old device that's probably out of production at this point but still supported by Wemo. I've been running with this for awhile but finally got around to contributing the changes after cleaning them up.

@esev could you please take a look at this when you get a chance.
Thanks!

Just a few lint issues found. See the details in the failing checks.

I think just running isort & black should take care of them. There is a scripts/build.sh file that should take care of running these too.

Thanks! Should be fixed now.

I pushed a few more pylint/flake8 updates to this PR. build.sh completes successfully now.

The current check failure is unrelated to this PR. I've fixed the underlying issue in #294.

Thank you again for this PR @alexanv1

I created a new release, version 0.6.8, that includes your change.

One more thing, @alexanv1 . If you have time, please consider contributing an integration test for the CrockPot. This helps us validate changes when we don't have the device to test with. We use the vcr library to record/replay the actual request/responses from the device.

See #205, #207, #208, and #214 for examples.

@esev, thanks for merging and releasing the update!
Sure, I will see if I can add integration tests within the few days if I have some time to figure out the vcr library.

@alexanv1 just FYI I bumped the pywemo version in Home Assistant. It includes this PR now.
