Add support for multiple Kogan devices

[Mantrid42]

These devices have all been tested to work with my Kogan devices. Some caveats:

1. I'm ignoring the bitfield reporting for air_quality (125) since it reports data; mostly to see if it ever changes
2. Ignoring the bitfield reporting for left_right_freeze (127) because the bitfield says it's not supported but it definitely is and works
3. I barely have any "optional" tags, so the feature set would have to match exactly
4. I don't have any "hidden: unavailable" tags because they never get hidden when adding the devices

It would be better to split these into individual PRs. The smartplug configs seem identical to existing configs, and both air conditioners seem to be broadly compatible with the fisher_summer config, but I haven't looked into the details like presets available. Quite likely the air purifier is an easy addition, the vacuum is very close to both the lx8 and lx10 and possibly could be merged with one of them, or the liectrex model that is also very close.

Sorry, I'm still a newbie with this stuff. The fisher_summer config is missing a bunch of things, and has things that don't work. I can do separate pull requests if you'd like, and add comments for what's different or otherwise why I made a custom config. The IP44 switch has two outlets, and one or two of the ids were different. The other smart switch may have just been that I didn't like it adding things that don't exist, most because "hidden: unavailable" doesn't work. I figured a direct ID match would save people the same trouble.
