Closes #34

This PR updates the PJM CWL v1.0 Conformance Tests, and adds the MPICH-sr workflow logs for Fugaku. All with cwltool only.

Re-ran the CWL v1.0 conformance tests using an interactive PJM allocation.

MPICH-sr workflow from the thesis was executed successfully on Fugaku without containers.

With Singularity, cwltool issues singularity pull --force for the image in the PJM node, which seems to have setuid or some other command/access restricted. Maybe building/converting Docker containers on PJM is not allowed (quite common in HPCs).

There may still have a way to instruct cwltool to use a pre-downloaded image and the workflow to succeed that way, or to run without pulling images, but I did not have time to try that (the last job finished near 2AM last night 😪 ).

The results are looking really good, and so far there are no real technical barriers for using cwltool on Fugaku, IMHO.

I will update the CWL Conformance Test README in another pull request, where I will try to add a Changelog too, to keep track of changes since the thesis publication.
