Issue 72

[tngTUDOR]

In python 3.9.2 the encoding keyword argument in json.loads has been removed (it was deprecated since 3.1). This patch does 2 things:

• removes the use of the keyword argument
• updates an assertion statement in a test that was failing. The failure was because of an assertion comparing unsorted lists of entries coming from os.listdir

I updated the test so that the PR Is "test" compliant ;)

I tested the branch code with both 3.8 and 3.9. Maybe presamples is ready to officially support "3.9" (add the classifiers to the setup tools)

@PascalLesage should I add a version bump commit to the PR ? I didn't see a "develop" branch, so I targeted the PR to master.

@tngTUDOR Excellent, thank you. Yes, you can add a version bump to the commit, that would be great. I'll also create a dev branch for next time.
