Create notebook to compare measurements from two sensors

[danieltsoukup]

Building on the starter notebook, create a template for comparing noise measurements from two sensors over a given period of time.

1. Include selectors for the two sensor ids and the time periods.
2. Make sure there is an adequate process for aligning the time stamps on the two sensors. Explore different options for this.
3. Calculate summary statistics over the difference in measurements for both min, max and mean. Average deviations, largest differences, distribution over time, etc
4. Visualize the results.
