Formatter fixes

split off the bugfix branch

Yes it looks weird. But it is the best way I've found after trying various hacks.

I hesitated making a commit for this:

But if people really have this use case maybe they should be using the API directly. It was useful for me to test:

import os

from decimal import Decimal
from weboob.tools.json import json, WeboobEncoder

print(json.__file__)
# This test should be ran with and without simplejson available
print(json.dumps(Decimal('1.1'), cls=WeboobEncoder))
