CarpetIOHDF5: support automatic gzip dataset compression
With the new steerable integer parameter IOHDF5::compression_level users can
now request gzip dataset compression while writing HDF5 files: levels from 1-9
specify a specific compression rate, 0 (which is the default) disables dataset
compression.
