Embrace Python types and modules in PySide

Create tutorials or specialized API to interact with common Python types:

• Numpy The project has support already for NumPy arrays, so one could generate a QMatrix from a 2D-numpy array, for example:

  num_mat = numpy.eye(4)                                                                         
  num_mat.shape = 16                                                                          
  unit = QtGui.QMatrix4x4(num_mat)                                                            
  assert unit == QtGui.QMatrix4x4()
  

• Pandas a new example using Pandas was included in the repository https://code.qt.io/cgit/pyside/pyside-setup.git/tree/examples/external/pandas and also an live example was shared during the QtWS2019 https://www.youtube.com/watch?v=214TWASZVgA

• pathlib compatibility: There is currently an effort to accept Path objects (from Python), everywhere we accept QUrl, QFileName, etc https://bugreports.qt.io/browse/PYSIDE-1499 (in progress)

There are currently more ideas to provide support for other types from different modules, but that will be followed up on a different EPIC.
