Typo in docs

[guettli]

There is a typo in the docs at https://sap.github.io/PyRFC/client.html

The example source code starts with these two lines:

except ModuleNotFoundError as e:
    from configparser import ConfigParser

This does not make any sense.

Maybe something like this would make sense to support Python2 and Python3 (untested)

try:
    from ConfigParser import ConfigParser
except ImportError:
    from configparser import ConfigParser
