This release introduces additional configuration/functionality for visualising bonds:
- `bond_radii_scale`: Factor to scale atomic radii by, when computing bonds (via overlapping radii)
- `bond_array_name`: The name of a boolean array on the `ase.Atoms`, specifying which atoms that bonds should be drawn for
- `bond_pairs_filter`: A list of bond element pairs to filter by
- `bond_color_by`: How to color bond: 'atoms' (same as connecting atoms) or 'length'
- `bond_colormap`: The matplotlib colormap to use with ``bond_color_by='length'`
- `bond_colormap_range`: The matplotlib colormap normalisation to use with ``bond_color_by='length'``
Also, document testing was moved to CircleCI and numpy pinning was bumped to 1.19
