STDPeriph I2C driver probably needs patching to allow null writes as well. Can you please check?

no need to patch "driver/bus_busdev_i2c.c" and "driver/bus_i2c_soft.c" because they are using for-loops based on paramater "len" [... for (i = 0; i < len; i++) { ...]. so it should work... but how can i test it? any other i2c-drivers out there?

Add the ultrasonic sensor GY-US42 as a new rangefinder to inav.
Because of the sensor's i2c trigger write command (only point to the register and restart), there was the need to patch the Method "drivers/bus_ic2_hal.c-> i2cWriteBuffer(...)" for passing through null values to HAL_I2C_Master_Transmit (raw access).
