#2836: add support for different data types to GPU arrays

Reporter: Roland Haas Status: new Milestone: Version: Type: enhancement Priority: major Component: EinsteinToolkit thorn

This adds proper support for data types other than `double` to CarpetX, also for GPUs.

It introduces a helper class `AnyVector`that can hold any data type (similar to `gdata` in CarpetLib), as well as a number of switch statements to handle openPMD's typed output routines.

I am told that very new versions of openPMD-api lets one call the internal un-typed output routine, but at the time this code was written, that was not yet possible, and thus may not be possible on all cluster installed copies of openPMD.
