Debug mode triggered after importing fdk #114

Description

Logging level changed to debug after importing fdk. This is possibly due to this line in log.py.

Steps to reproduce the issue:

import logging
print(f'DEBUG level = {logging.DEBUG}', )
print(f'Current logging level = {logging.root.level}')

import fdk
print(f'Current logging level = {logging.root.level}')

Describe the results you received:
Logging level does not equal to DEBUG before importing fdk but is changed to DEBUG after import.
