[67] Novelty dashboard charts

[beingkk]

Closes #67 Closes #73

Description

The main contributions of this PR are:

• utils/novelty_charts.py: New utils for producing novelty charts
• novelty_chart_examples.py: New notebook with output tables/charts and text descriptions

Hope this helps in implementing the charts in the streamlit dashboard!

I've tried to refactor as much as possible of the chart and table production to the novelty_charts.py

I've also added text descriptions describing the methodology and interpretation of the charts. Hope they are clear, but please feel free to adjust.

NB: Unfortunately I'm not here for the remainder of this week and next week (taking leave till first week of April). Of course happy to make adjustments to the PR when I come back in April, but I appreciate you'll want to move faster and merge it already. I hope it's OK for you to make any essential changes yourself? Thank you!

Just FYI, I have refactored the code and added also time series charts.

I will add text descriptions in the notebook tomorrow morning, which will help explain what each chart is showing.

Hope this will be useful!
