How to use the configuration outside MMEngine.

[vincrichard]

Hello and thank you for the hard work on MMengine.

The configuration framework of MMengine is quite powerful, and using pure python has a strong advantage. Being able to use it outside the strong dependencies of MMengine as a whole would be quite useful for smaller research project.
A minimal implementation of the Config class with the pure python logic would be a blessing.

Does any project exist ? Would it be possible, in the future, to expect the configuration as a separate module similar to what Hydra is today but with a different design logic ?

Cheers !
