btlogging setLevel does nothing

[thewhaleking]

from bittensor.utils.btlogging import logging

print(logging.get_level())  # prints 30
logging.setLevel(20)
print(logging.get_level())  # prints 30

I would expect this to set the logging level to 20, but it does not.

If this is expected, it should be documented (LoggingMachine subclasses logging.Logger, and thus has that method.)
