TuyaMCU driver relative humidity should behave as temperature WRT tempres

DO NOT DELETE ANY TEXT from this template! Otherwise the issue will be auto-closed. -->

PROBLEM DESCRIPTION

Relative humidity fnids are affected by tempres - value is padded with extra number of zeros. This results in inaccurate values if tempres is not 0. Before 9.3.0 we had similar issue with temperature - issue 10917

TO REPRODUCE

Get humidity reading with device using fnid 73/74 Note TuyaMCU always returns an integer

EXPECTED BEHAVIOUR

The value in the web interface should not be padded with extra zeros. Tempres puts the decimal in the correct place

SCREENSHOTS

ADDITIONAL CONTEXT

I think the fix is to route the humidity values through the same function as the temperature which divides the value based on the tempres value. I will submit a PR with this behaviour and update the docs as with the temperature
