Use plotly shapes to add underlays to plots. Preferably use with telemetry endpoints.

Testing instructions:

1. Create a scatter plot

2. Select an underlay json file Example:
   Underlay.json.zip

3. Ensure that the underlay has been rendered on the plot

4. If min/max ranges for X and Y axes were provided, they should be correctly used in the plot as well.
