footmark latest version (1.20.0) can not work with the latest Python (3.9)

[schrht]

...
  File "/home/cheshi/.local/lib/python3.9/site-packages/footmark/connection.py", line 426, in get_status_new
    body = json.loads(body, encoding='UTF-8')
  File "/usr/lib64/python3.9/json/__init__.py", line 359, in loads
    return cls(**kw).decode(s)

We are seeing this error because the argument encoding was removed from json.loads in Python 3.9 (it was deprecated since Python 3.1). Python 3.9 was released in October 2020.

So please update the code of footmark to be able to work with Python 3.9.
