New Integration: SMLIGHT SLZB-06 Adapters Integration

[tl-sl]

Breaking change

Proposed change

SMLIGHT make a range of USB and LAN Zigbee coordinators. The LAN coordinators are based on ESP32 and have an onboard web UI. This integration aims to bring support for monitoring and managing these devices directly into Home Assistant. Providing direct access to sensors, switches, buttons and other features that are available from the SLZB web interface. There is no actual Zigbee support within this integration as that is handled per normal with either ZHA or Zigbee2MQTT.

Planned features:

• Management of device features (mode switch, restart, disable led's etc)
• Update sensors for both core firmware and zigbee firmware on SLZB-06 device
• Full coverage of various sensors available on device
• Configuration of language and timezones
• Firmware management for USB devices (SLZB-07)

This initial PR contains only a very slimmed done set of features for minimal usability for intial PR:

• Manual user config flow
• Zeroconf config flow
• Sensors platform including temp sensors, memory usage stats.

All variants of SLZB-06x are supported:
https://smlight.tech/product/slzb-06/#

Currently this integration requires SLZB-06 to have the v2.3.6.dev core firmware or later installed, a later PR will add support for slzb-06 with factory or older core firmware versions to allow the user to directly upgrade to a version that fully supports this integration.

This integration is supported by SMLIGHT. code by @darkxst

Hello. I had some time to test your new SMLight integration on my SLZB-06p10.
The integration was set up via Zeroconf.

Please tell me if you need more tests.
Thank you for your work! 💙💛
