Fix for logging in ratelimit.py

[nevermort]

Hi folks, could you please explain for what purpose the logging library is used in ratelimit.py in that way?
import logging ... logging.debug('\t__init__: name=[{!s}]'.format(self.name)) ...

I'm experiencing a quite funny issue, any time I invoke vulners.Vulners() my root logger getting reconfigured. So I am forced to delete added Handler any time I'm using the module.

Perhaps it will be a better solution to create a dedicated logger for the module and do not use root logger?

Thanks in advance.

I'd be grateful if you update the PyPI package in case my PR is applicable and appropriate for you
Thx.
