Handle multiple same data sources

#Description

The DataSource interface #4 should handle multiple of the same sensor.

Use case

What if we are using several temperature sensors at different locations around the craft and they are all the same?

Design notes

1. There should be a way to uniquely identify sensors of the same type. This might be possible by writing a unique value in an unused writeable register on the sensor device/microcontroller.
2. Any unique identifier should be in the DataSource object created for the corresponding sensor.
3. This might require writing a more sophisticated version of poll (see Define a DataSource interface as the basis for telemetry gathering #4).

For the senior project, we are unlikely to have sensors of the same type.
