Update AdditiveFoam spatial and temporal registration

[gknapp1]

• Spatial registration: Currently AdditiveFOAM is configured to simulate every layer at Z=0, regardless of the information in the scan path file, and ExaCA is configured to expect this behavior. This results in AdditiveFOAM and ExaCA results being registered to the build data coordinate system in X and Y, but not in Z
• Time registration: In some scan paths files, the first "wait" instruction can be specified to sync the scan path with the elapsed in-layer time. This is currently ignored in AdditiveFOAM (see fixup: address bug in additivefoam app #118).

The templates and default behavior for the apps in Myna could be updated to correct these to register simulation results to the build data in both time and spatial coordinates. These would have to be done in conjunction with any required changes to AdditiveFOAM and ExaCA.
