edit the accuracy_decimals from 0 to 1 for the humidity/temp/ so that users dont have to edit the code to see humidity to tenth place

[bharvey88]

sensor:

• platform: sen5x
  id: !extend sen55
  #Humidity accuracy change
  humidity:
  name: "SEN55 Humidity"
  filters:
  - lambda: return x - id(sen55_humidity_offset).state;
  accuracy_decimals: 1

I propose we change the accuracy_decimals from 0 to 1 for multiple entiites.
