Upgrade code to use hdf5 1.14
HDF5 1.14.x is now the only officially supported version. We should transition.
Possible caveat:
- Master code (no changes) seems to be hanging when reading data with hdf5 1.14 in parallel with the latest ICX (2022.3.0) and UCX 1.10. Works fine when swapping to hdf5 1.12.0.
