Macos fixes for ci

See merge request !227

* force .so for extension SWIG'ed PythonAnalysis module on MacOS. This seems to
  be necessary for the import to work and is consistent with CMake's
  PYTHON_ADD_MODULE function

* Use RPATH so that the SENSEI library directory need not be in the
  LD/DYLD_LIBRARY_PATH when importing the senseiPython module. However, note
  that we still need the SENSEI library directory in the PYTHONPATH.

fix a crash when compiled against Debug build of VTK

See merge request !226

If you set an array named vtkGhostType it is cahced in vtkDataSet. Any
chnages like removing this array or renaming it require that cached
value to be updated otherwise an assert will crash.

Adios2 in transit

See merge request !221

note about the ADIOS tests: There is a flag to enable adding sender and
receiver block owner arrays to the metadata. These arrays are generated
in the data adaptor and are useful for validating M x N partitioning
behavior. The regression tests color by them. However, reporting them in
the metadata breaks the numbering scheme. Therefor, the flag must be set
manually in the source code and it is off by default. the images
rendered by the tests do not show the partiioning unless the flag is
set. One can however examine the terminal output to verify partitioning
as it is sent to stderr as the test runs.

the adios2 2.5.0 api uses size_t, but we had used uint64_t.
the issue came up on MacOS w/ Clang.

sensei 3.1.0

See merge request !206

Ascent analysis adaptor 3 development

See merge request !204

this addresses some of the more glaring issues w/ the ascent
analayis adaptor. The mesh name, array name, and centering are
now specified via XML DataRequirements. Removes the switch on data
set type in the array transfer code as arrays are handled from the
base data object class. adds some FIXME statements to document
what remains to be done.

This patch renames diy to sdiy. It modifies diy itself,
renaming diy namespace. Also installs our embedded copy of
diy into sdiy. this should help isolate us from others who
embed diy.

Removed tbb.cmake from make_install. Moved the Ascent test app to the sensei/testing directory. Made changes to AscentAnalysisAdaptor.cxx per Burlen request. Removed the use of format.h/format.cc from the Oscillator miniapp. The format code would colide with diy use of format. Remove message about using a different DIY from diy.cmake.
