Latest versions of packaging break QDAC2 driver

[maij]

Somewhere in the recent changes of packaging, using packaging.version.parse on strings like 'w-x.y.z' raises an error about an invalid firmware version. Explicitly installing an older version (I used packaging 20.0) circumvents this issue.

@maij This was resolved in #180 and will be part of the next release

I just created a new release that should be available from pypi soon

@maij if you can confirm that resolves the issue we can close this one

Have not heard back so assuming this is indeed fixed by latest release
