token validation fails with pyjwt>=2.10

[simontaurus]

mediawiki uses numerical values for subjects, e.g. "sub": 4.

Since version 2.10 pyjwt enforces subject to be of type string, see jpadilla/pyjwt#1017

This makes jwt.decode failing with Exeption: Subject must be a string

python-mwoauth/mwoauth/functions.py

Line 231 in 2cb6b71

identity = jwt.decode(r.content, consumer_token.secret,

Workaround:
Downgrage pyjwt<2.10

Solution:
set options = {"verify_sub": False} for jwt.decode
