can't read openPMD files that use the ADIOS2 format

[BenWibking]

Bug report

Bug summary

The openPMD frontend only reads openPMD files that use the HDF5 format. openPMD files that use the ADIOS2 format cannot be read by yt.

The openPMD-api (https://github.com/openPMD/openPMD-api) provides a Python package that can be used to read any openPMD file, regardless of the backend format chosen.

Code for reproduction

Actual outcome

Expected outcome

yt should be able to open all openPMD files, regardless of the backend used.

Version Information

• Operating System:
• Python Version:
• yt version:
• Other Libraries (if applicable):

I am happy to help add support for using openPMD-api, but I don't want to duplicate effort if someone is already working on this.

Hi Ben. For what it's worth, I haven't heard of anyone take else working on this already and I'm sure this would a welcome addition. Thanks !

I haven't had a chance to work on it, so it's all yours to work on if you wish.
