v1.4.0

This release adds controls and sensors for CTS602 devices with central heating as requested in #25
The controls allows for setting the heating mode, pump mode and selecting the source of heat.
Supply (T14) and return (T13) temperatures are added as sensors.

The sacrificial anode sensor have been corrected for CTS602, it was assumed to be a binary sensor. However it has four states. Thus the previous binary sensor has been changed to a new normal sensor with the correct values.

Issue #24 with the supply air temperature for CTS602light has been resolved.
As part of the solution the sensor for "after heater" is removed for CTS602light, as it never had two sensors.

Issue #23 is fixed. Fan RPM extract is no longer mistakenly divided by 10 for Optima 270 devices.

Improvements have been made to the selection entities. These now support translations and are thus now also translated to danish.
