Workaround for this bug: openPMD/openPMD-api#1794
I think that this has little importance for PIConGPU since we process Iterations collectively anyway, making it unlikely to happen.
But I did stumble over this issue a while ago. Of course I did not document it and have no reproducer at hand now…
TODO:
.writeIterations()with.snapshots()and usingWRITE_RANDOM_ACCESSmight trigger the issue, but in that case it would be restricted to dev versions of openPMD, hence not so important.
