Custom configuration

[astro]

Hi

Firstly, thanks for the small and useful logging library.

I don't want to confront users with an nlogger.json file that requires knowledge of the module names. Also the current working directory isn't always the project root.

It would be super-cool if configuration could be set from the JS side, without the confusing message whenever nlogger.json cannot be found.

Thanks a lot,
Astro
