Add Sonoff SNZB-06P presence sensor support

[peterkh]

Proposed change

Improving the support for the Sonoff SNZB-06P

Main changes by this quirk:

• remove redundant IaS Zone cluster as it doesn't provide anything useful that is not already provided from the Occupancy cluster and removes a second entity being created.
• Adds support for Sonoff specific cluster which has the illumination state (Light or Dark) when presence was last detected.

Additional information

Thanks to @theorlangur and their work on #2869.

When combined with home-assistant/core#107379, solves #2702

Checklist

• The changes are tested and work correctly
• pre-commit checks pass / the code has been formatted using Black

@TheJulianJES just wanted to check if there is anything more I need to do with this quirk before it can be reviewed? If its just in the queue, all good and apologies for the ping :)

[TheJulianJES]

It's still on my list to review. The changes look good from a quick glance though.
