Create interactive fuzz plot artifacts

[cdummett]

Currently plots from the fuzz-test runs are created using matplotlib and saved in the .jpg format. For long runs it becomes difficult to "zoom in" on a small section of the run, e.g. artifact.

It would be better if artifacts were saved in an interactive format, e.g. .html files created using either mpld3 or plotly.

The disadvantage to saving as .html files is they are not directly viewable as Jenkins artifacts. It may be worth saving the plots as .jpg files and storing the interactive .html files in a separate folder.
