Add events for bracket updates

[enchantinggg4]

It would be nice to emit events when entities actually change, for example after setting
manager.update.matchGame(...) i need to manually compare match before and after to detect if it has changed(for example, finished).
Change events are essential in distributed systems, e.g. publish to message broker event that "bracket match changed", "stage updated" and etc

I'm up to providing a PR since its needed for my project

Hi! That's a good idea, you could extend the BracketsManager class from EventEmitter and use what I had done with the verbose mode here:

brackets-manager.js/src/manager.ts

Line 162 in d8a5f5e

private instrumentStorage(): void {

Hey @enchantinggg4! Did you start working on it? Otherwise I can find time to implement it. (I just don't want both of us to spend time on it)
