add ability to choose time array for pio reader
pio files can now choose to use cycle number or simulation time as their time array. a combo box for time array is added under the list of variables to load.
Depends on VTK merge request vtk/vtk!6975 (merged)
Right now this has issues in the GUI:
- When initially choosing a time array that is not the default, it will not work. The default time array will always load and be listed in the "Time:" combo box at the top.
- When loading a new time array after initially loading the file, the "Time:" combo box at the top that lists timesteps will not update.
These issues are present in the release branch, but everything works fine in the master branch. I believe merges that @yohann.bearzi put in, for Paraview issue #19376 (closed), have resolved these problems in the master branch. Is it possible to cherry pick them and add them to the release branch?
