Description
Describe the bug
Some HDF5 Datasets written on x86 platforms cannot be opened on ARM and PowerPC architectures.
To Reproduce
Use either:
Be_dens.zip
or:
https://github.com/openPMD/openPMD-example-datasets/blob/draft/example-femm-3d.h5
and try opening it on a PowerPC system (e.g. Summit) or an ARM system (e.g. modern Apple devices) with openpmd-ls.
Expected behavior
> openpmd-ls Be_dens.h5
openPMD series: Be_dens
openPMD standard: 1.1.0
