Problem Description

Create a new feature which basically allows the users to hot-reload their configs files. Which means that new values are going to be applied when the config is updated.

Proposed Solution

Considered a zero deps solution for this or directly use notify, using notify would be a painless solution in my opinion.

I'm starting to reconsider this because I want forgeconf to be lightweight, and adding a file watcher is completely contrary to what I'm aiming for.

I can still add an example of how to easily add a watcher the forgeconf tho.
