[BBPBGLIB-1063] nerodamus holds logging

[WeinaJi]

https://bbpteam.epfl.ch/project/issues/browse/BBPBGLIB-1063

User reported that it is not possible to set the logging level after import neurodamus is used.

this prints:

import logging
logging.basicConfig(level=logging.INFO)
import neurodamus
logging.info("bau")

this does not print:

import logging
import neurodamus
logging.basicConfig(level=logging.INFO)
logging.info("bau")
