Error while setting log level

[clubby789]

from pwn import *
context.log_level = 'silent'

Traceback (most recent call last):
  File "/tmp/test.py", line 3, in <module>
    context.log_level = 'silent'
  File "/usr/local/lib/python3.9/dist-packages/pwnlib/context/__init__.py", line 173, in fset
    self._tls[name] = validator(self, val)
  File "/usr/local/lib/python3.9/dist-packages/pwnlib/context/__init__.py", line 974, in log_level
    level_names = filter(lambda x: isinstance(x,str), logging._levelNames)
AttributeError: module 'logging' has no attribute '_levelNames'

This appears to be left over from Python 2's logging module, which had logging._levelNames:
{0: 'NOTSET', 10: 'DEBUG', 'WARN': 30, 20: 'INFO', 'ERROR': 40, 'DEBUG': 10, 30: 'WARNING', 'INFO': 20, 'WARNING': 30, 40: 'ERROR', 50: 'CRITICAL', 'CRITICAL': 50, 'NOTSET': 0}.

Python3 has logging._levelToName: {50: 'CRITICAL', 40: 'ERROR', 30: 'WARNING', 20: 'INFO', 10: 'DEBUG', 0: 'NOTSET'}

Ironically erroring 2 lines before throwing an error
