Add support for Hornbill Y4 Smart Lock family

Adding support for Hornbill Y4 Smart Lock family.

Here are the query results:
query_things_data_model.json
query_device_details.json

This was based on #1830 and #2824, but I still need to understand some parts. Maybe @rudironsonijr and @josefelixh can chip in?

@make-all I'm trying to run test_device_config.py locally but I always get this:
ModuleNotFoundError: No module named 'custom_components.tuya_local'

I'm in a venv and installed all the modules using requirements-dev.txt. I also tried to add custom_components/ and custom_components/tuya_local/ in PYTHONPATH without any success.

What am I missing?

I don't need to add anything to my PYTHONPATH to run pytest. To run the utils with python, I need to add . to PYTHONPATH though.

So you simply run python3 tests/test_device_config.py?

Adding . seems to get me further, but now I get:

Traceback (most recent call last):
  File "/home/jpare/git/tuya-local/tests/test_device_config.py", line 22, in <module>
    from .const import GPPH_HEATER_PAYLOAD, KOGAN_HEATER_PAYLOAD
ImportError: attempted relative import with no known parent package

My bad, I need to use pytest tests/test_device_config.py. Still a couple of TODO in hornbill_y4_smart_lock.yaml I need help with.
