New board : OWNVERTER_V_0_9
As we developped a new board OWNVERTER_V_0_9, code must be updated with at least the followings:
- A line OWNVERTER_V_0_9 should be added to the the hardware_version_t enum in the file HardwareConfiguration.h
- Update PB11 assignation. It is now an ADC input (ILOW3) (on twist it is a DAC output).
