added Plotly materialization example

[zilto]

Added a new example folder plotly with instructions on how to use the previously added materializers found in plotly_extensions . There are a few important practical tips to manage the size of generated HTML files.

Changes

Added a notebook to generate figures with the materializers and a README with notes.

How I tested this

Run the notebook end to end
