panda-shortname doesn't work with period datasets

[kratsg]

I expected this to work:

./panda-shortname data16_13TeV:data16_13TeV.periodI.physics_Main.PhysCont.DAOD_SUSY10.grp16_v03_p3372

but it doesn't since the dataset ID is periodI instead of a number (somewhat unexpected but...)

I've done the somewhat useless thing here and added a help wanted label.

To maybe pick up this Issue again soon:

$ docker run --rm -it -e USER="${USER}" python:3.8 /bin/bash
# python -m pip install --upgrade -q pip setuptools wheel
# pip install -q pandamonium
# pip list
Package      Version

    oname = process_name(ds_name, args.remove, args.prefix, args.suffix)
  File "/usr/local/lib/python3.8/site-packages/pandamonium/panda_shortname.py", line 74, in process_name
    assert dsid.isdigit(), "dsid ({}) not a number".format(dsid)
AssertionError: dsid (periodI) not a number

So currently looking at the code

https://github.com/dguest/pandamonium/blob/2c9951664b541199120530dd0df838086f6c4e4f/src/pandamonium/panda_shortname.py#L73-L74

it seems this could be addressed with an or.

This example is also probably good as a unit test.
