Add Centralite 3157100 thermostat quirks

[presslab-us]

This thermostat does not report battery_percentage_remaining,
like most other Centralite devices.
Use the existing code to convert from battery_voltage.

There is a pylint error Module name "3157100" doesn't conform to snake_case naming style (invalid-name), but it's named similar to the other files in that folder.

Update this: https://github.com/dmulcahey/zha-device-handlers/blob/52f480ee595d69f4629c35333436bbf73c0a3170/pylintrc#L53

I also found this which seems to work too. Which would you prefer? Is it required to be in the pylintrc file also if this is in the module file?

Either one, I’ll eventually take a pass through all of this to clean this up.
