Add metadata sensor / camera analysis to LADI Tutorial

[aweinert-MIT]

Add to the LADI tutorial, the code and workflow to calculate the histogram or relative frequency of different sensors / camera models. The tutorial should demonstrate how to query all the data for a few columns, do some basic processing (e.g. remove NaN elements), and the visualize the results.

This issue can be enhanced by determining the distribution of image filesize as a function of a specific camera or determining if the average or median filesize has increased overtime.

The Examples_Metadata should be updated with documentation and explanation on how to complete the task. Also create a .py file in Tutorials/Model_Script as reference code to complete the desired analysis.
