bindings for reading particle data

[BenWibking]

Is there an appropriate C++ API that can be used to read particle data, similar to #320?

The use case is to visualize particles with plotfile-viewer: https://github.com/BenWibking/plotfile-viewer.

Hi @BenWibking,

The code for reading particles is the Restart method of ParticleContainer, implemented here. There's also a test that shows how to use it here.

@atmyers thanks!

@ax3l @BenWibking is there any progress on this? If not, what can we contribute to speed things up?

Status is as follows: #320 merged two days ago and in 24.07 release.

The linked methods from Andrew's post are very easy to add. Please go ahead and post a PR - contributions are super welcome 💖. I am on PTO and back on July 15th, so this can totally land in 24.08 if someone takes the lead to add a few more .def method bindings and a good test 🙏

Should be closed by #342 (except for any app-specific template instantiations).
