[ANN] Mayavi-4.6.1 release

[Prabhu Ramachandran]

Hello,

We are pleased to announce Mayavi-4.6.1. Mayavi is a general purpose,
cross-platform Python package for 2-D and 3-D scientific data visualization.
Mayavi integrates seamlessly with NumPy and provides a convenient Pythonic
wrapper for VTK (http://www.vtk.org). It provides a stand-alone UI to help
visualize your data. Mayavi is easy to extend and embed in your own dialogs
and UIs.

- Make the use of an extension module optional. This allows installation via
  pip without needing to have a compiler.
- Fixed installation with pip when numpy is not installed.
- Support for PySide2.
- Add methods to make it easy to add attributes to datasets.
- Fixed several issues.
