drop python2 support in wmi.py and ese.py

[NtAlexio2]

This PR adds ordereddict module to requirements in order to references here (wmi.py) and here (ese.py)

---

EDIT:
Since new recent versions of Impacket doesn't support Python2, we can safely remove ordereddict module referenced here (wmi.py) and here (ese.py)

Tip: ordereddict module needs manual installation.

Does this make sense? OrderedDict is part of the standard library since Python 2.7. I think the try-except compatibility import of the ordereddict package is only to support ancient Python < 2.7.

Given that setup.py lists impacket being compatible with Python 3.8+ only, I think it would make sense to drop the ordereddict compatibility import instead and just use from collections import OrderedDict everywhere.
