Sensor: Design sensor data struct for Rev 3 and implement sensor_dump

**Requester: @ETSells **

**Describe the solution you'd like**
We need to implement the core data structure for Rev 3, and have a routine to populate it.

**Additional context**
Design should be reviewed by @ETSells and @NArmistead to ensure the two flight projects can continue to be maintained side-by-side.
