Sonoff Trvzb: expose new attributes of firmware 1.3

[danielkleinert]

Proposed change

This change exposes new attributes of the current firmware.

Values are adopted from zigbee-herdsman:
Koenkk/zigbee-herdsman-converters#8837
Koenkk/zigbee-herdsman-converters#8873

I am unsure about the naming. Hysteresis could be better than "Temperature control accuracy".

Checklist

• The changes are tested and work correctly
• pre-commit checks pass / the code has been formatted using Black
• Tests have been added to verify that the new code works

@danielkleinert I’m still waiting for confirmation from Sonoff, but I'm starting to think the "external temperature sensor" attribute is a bit field rather than a simple on/off. See my comment here: Koenkk/zigbee-herdsman-converters#8873 (comment)

[danielkleinert]

@photomoose Thanks for letting me know. I'll try to map that once you get the confirmation on the semantics.
