Fix level enum checking

In Python 3.8 checks with non-Enum causes TypeError exception.
https://docs.python.org/3/whatsnew/3.7.html#enum

So, if the library user would call mdclog.set_level(123)
it would crash the process with Python 3.8. With 3.7 it would
just cause an error print and with older nothing would happen.

Now we try to convert the set_level argument to a Level object
and if it does not succeed then ignore the setting, like
it has worked with older Python versions.
