Very helpful.  Thanks for the quick turnaround.
Now I go off in a corner with an internet connection for quiet time ...

Then pickup and install both the LZ4 and BitShuffle filters.  Now make sure HDF5_PLUGIN_PATH is defined to point to the directory containing the filter libraries.  Then h5dump should be able to handle the Eiger files.
