Add JDFTx jobs.py to run JDFTx using atomate2/jobflow

[soge8904]

Summary

Hi,
This PR is to add jobs.py for JDFTx. We have a draft PR open on atomate2 to integrate JDFTx, but it seems that this script belongs here. Jobs.py was created using the CP2K template, with only the basic functionalities for now (just enough to run a job).
