Plotly.NET v4.1.0

This is a maintenance release that aims to keep up with plotlyjs 2.x incremental updates.

The only major change is the usage of Giraffe.ViewEngine.StrongName instead of Giraffe.ViewEngine as html dsl.
This could be considered as a breaking change, but it's not because the Giraffe.ViewEngine.StrongName package is a drop-in replacement for Giraffe.ViewEngine with the only difference being a signed assembly
