TPlink - KP200 (Wall outlet support)

Would be great to add support for the relatively new TPlink KP200 (smart wall outlets) to HomeAssistant.

The KP400 dual-outlet outdoor switches are probably similar to support. Right now they show up as a single switch (which turns both outlets on) and do not read status from the two outlets properly (meaning it’s hard to turn both outlets back off). @rytilahti

KP200 and KP400 support would be amazing. I have a KP400 and cant use it in HA right now

I just created a PR that fixes this as a custom_component for me and my KP400 devices:
