register custom integration

Breaking change

Proposed change

The change registers a custom integration for the Philips brand. The integration is published via HACS and is the leading integration for Philips Air Purifiers: https://github.com/kongo09/philips-airpurifier-coap

Goal is to group everything that belongs to the Philips brand together. I'm not aware if there are alternative ways to do this for custom integrations or if custom integrations are not meant to be included (which would be a shame as that would reduce the user experience).

Edit: the local test fails, so this doesn't seem to work. Feel free to reject, but I'd be grateful for a hint how to fix this.
