Xopt Asynchronous Xopt does not make a dump file

Hi, I recently updated my xopt from 1.4.1 to 2.2.2. I noticed that running Xopt in parallel (processes, threads, MPI) does not make a dump file anymore. This makes it difficult to see the data and resume halted optimizations.

I'm running https://github.com/ChristopherMayes/Xopt/blob/main/docs/examples/basic/xopt_parallel.ipynb The only modification I made is adding dump_file: dump.yaml to the initialization file.

It looks like this is a bug: https://github.com/ChristopherMayes/Xopt/issues/235

@ndwang What generator are you using? CNSGA now has its own population file output, which you can restart with. You don't need the dump file for that.

@ChristopherMayes Thanks for looking into this. I found xopt.utils.read_xopt_csv can parse populations files easily and do basically the same thing. I just really liked X = Xopt.from_file('dump.yaml')
