Periodic system simulations

simulating periodic systems or slab with qiskit and pyscf

Hi!
I am wondering how can I simulate periodic systems using qiskit-nature-pyscf such as a slab of Si for example

I came across the issue in qiskit-community/qiskit-nature#988 where there was some refers that this newer repo can have the implementation for periodic embedding technique

The pipeline for simulating periodic systems has not been tested in the context of this plugin. That does not mean it does not work, I simply do not know.
If you do test it and find that it works, please feel free to contribute a PR which adds unttests (and any additional required changes) such that the support can be validated continuously.
