Fix debug level option

[johnmaia]

This PR fixes the debugnyan debug level option.

The current version always replaces the given level option by the default value and therefore does not allow to set a custom level.

Hi! Any updates on this? Thank you.

@waldyrious please take another look.

Not being able to set the level property is on purpose, we do not want debugnyan to log messages unless debug has the namespace enabled.

If the issue is that the level is to low, why not raise it? Would 999 work?

[johnmaia]

We would wish to be able to configure the debug level depending on the environment where our applications are running.

Example:

On our development environment we would set the debug level to DEBUG to have more detailed logs and on our production environment we would set it to WARN to reduce the amount of logs.

However, with the current version of debugnyan we are simply unable configure the debug level which, to me, is a pretty obvious configuration option on a debugging tool.

Ok, then it seems to me the only thing you want is to configure the level set here https://github.com/uphold/debugnyan/pull/98/files#diff-168726dbe96b3ce427e7fedce31bb0bcL61.

Changing the level on the other two lines (when creating the logger instances) would have the undesired effect of outputting the log messages even when their namespaces were not enabled.
