Implement dependency injection

[boesing]

This component does not really use OOP in most places and thus, providing logging and stuff is quite complicated.

To solve this, we can implement a dependency injection library.

I do quote the answer from @internalsystemerror here as he provided some information on how we could move over to dependency injection.

I'm mostly familiar with the DI in Angular, but there are (smaller) libraries available e.g. TypeDI or even TSyringe by MS

Does a bootstrap script not suffice? Like an entrypoint script? In theory, we don't need a DIC at all 🤔
