Improved ODB support (#8046)

* Experiments for supporting visualization of new ODB files from WIA workflow

* Some more experiments to get odb working for wia results

* More work in progress, experimenting to get wellIA result files to load properly

* Make sure all part geometries use the same global bounding box

* Clean up code

* Add some safeguards for data calculations
Move parts below grid in project tree

* Fix warnings

* Add support for C3D8RT elements
Add some more safeguards for missing data
Remove strange part handling

* Support elements with reduced number of integration points by pretending to have 8.

* Change integration point mapping to correct order (ref. Stein and Abaqus 2019 doc)

* Do not allocate too much memory for element nodal results for 20 element node types

* Code cleanup.
Revert back to old integration point numbering scheme (ref. Stein)

* And, another integration point order update...

* Update comments
