Treat range() as a simple array

[dniku]

Fixes #1798 (incorrectly closed during a recent cleanup).

Allows range() to be passed where simple arrays are expected.

Previously the following code

import plotly.graph_objects as go
go.Figure(go.Scatter(x=range(3), y=[3, 2, 1]))

failed with

(tested via Google Colab)

After this change, it is possible to use range() in this context.

A potential concern is Python 2 support — there, range() is a plain list. I have not tested this with Python 2.
