New Issue: Change halt in getHDF5Type into compiler error

16590, “daviditen”, “Change halt in getHDF5Type into compiler error”, “2020-10-15T17:56:58Z”

The function HDF5.getHDF5Type(type eltType) halts if it is called on an unrecognized type. Since types are compile-time information, it can and should issue a compilerError instead.
