Modbus Select entity support

Please, consider implementing the new Select entity in Modbus integration. I would love to have this to control my HVAC system - I can only control it from HA via Modbus TCP. Currently, setting temperature is no problem, but selecting mode of operation or some additional options is hardly possible, e.g. mode of operation is set in one holding register as follows:
0 - Off
1 - Auto mode
2 - Ventilation
3 - …
Select entity would be perfect for this.
