[x] openpmd-pipe seems to not work in parallel as it tries reading at some point
[x] test with picongpu
[x] Documentation
Idea: When using in parallel, just create files simData.json.parallel/rank_0.json, simData.json.parallel/rank_1.json, ... and so on. No direct support for reading, users need to either manually pick one of the JSON files or find some adequate tooling for merging them.
