Jupyterlab Streaming and New Features

This release, pyvista==0.27.0, is a major release that includes an important new feature for jupyterlab: real-time streaming leveraging ipyvtk-simple. Using either software or hardware rendering (as supported by VTK), you can visualize geometry on a remote machine through a jupyterlab environment!

Several other new features were added, along with many bug fixes and optimizations by both new and existing contributors. Thanks all for your contributions! pyvista would not be possible were it not for the community of developers behind all these PRs.

EGL Wheels

Attached wheels (vtk-egl-9.0.1*) are for hardware (GPU) based rendering on jupyterlab or headless instances. Wheels built with:

echo "Building with EGL"
$PYBIN=/usr/bin/python3.7
yum install mesa-* -y
git clone https://github.com/Kitware/VTK
cd VTK
git checkout v9.0.1
mkdir build && cd build
/io/cmake/bin/cmake -DVTK_BUILD_TESTING=OFF\
                    -DVTK_WHEEL_BUILD=ON\
                    -DVTK_PYTHON_VERSION=3\
                    -DVTK_WRAP_PYTHON=ON\
                    -DPython3_EXECUTABLE=$PYBIN\
                    -DVTK_OPENGL_HAS_EGL=True\
                    -DVTK_USE_X=False\
                    ../
make -j
$PYBIN setup.py bdist_wheel

There's also one vanilla Python 3.9 wheel since that's not currently available on PyPi.
