[modules] airspeed_ets: add 3rd party mode support

Browse Source 
Add option to use the raw value. This is needed when the sensor is in third-party mode.

Has only been tested with V3 of the sensor hardware.
Notes:
Connect directly to TWOG/Tiny I2C port. Multiple sensors can be chained together.
Sensor should be in the proprietary mode (default) and not in 3rd party mode.
Connect directly to TWOG/Tiny/Lisa I2C port. Multiple sensors can be chained together.
Sensor may be in the proprietary mode (default) or in 3rd-party mode. In 3rd-party mode you must define AIRSPEED_ETS_3RD_PARTY_MODE.
A eLogger is needed to set sensor to 3rd-party mode, which is supposed to be more reliable than the default mode.
