[WIP] Update IEEE conversion routine for tetragonal systems

[JosephMontoya-TRI]

Summary

Tentative fix for rotating tensorial properties for tetragonal systems.

TODO (if any)

• Need to add data for testing tetragonal system that previously failed
• Fix an issue with precision on prior test data

Hi @montoyjh,

Can you expand on this point:

Fix an issue with precision on prior test data

I don't mind adding an additional test here if necessary, but not sure what else required.

[mkhorton]

Bumping this because it seems like a serious bug. If there's no additional context for the precision issue, I'd like to go ahead and merge with a minimal test added for the problem system.

The tests need to be supplied first.

Seems like there might be more issues with the tensor rotations, as per my #3059
