Sensor subclasses

[abkfenris]

Make sensor subclasses for common types, to fill in standard column data when auto creating a sensor. Make a new_sensor() method that takes type and then will either use specific subclass or generic Sensor Class to create a new sensor. Also make stypes {} dict to convert common incoming sample types with different naming to Sensor subclasses.

• Sensor Common Subclasses
  • [ ] Level
  • [ ] Voltage
  • [ ] Amperage
• [ ] new_sensor() or sensor.init() that uses subclasses if available

Maybe just normalize sensor info coming in, and have a dict with appropriate values. Or maybe a default sensors table.
