Allow for "Baked-In" services to be overwritten

[CLeeSpruit]

Describe current status
As of writing, Vivi has 4 baked in services, ApplicationEvent, Logger, NodeTree, and ParseEngine.
While NodeTree and ParseEngine are pretty integral to Vivi and would likely not be touched, I can see ApplicationEvent and Logger being annoying for a user that would want a custom solution as ApplicationEvent uses Zephyr for event handling over something like say RxJS and a lot of people like rolling their own logging services.

Describe the outcome you'd like
Allow for custom baked-in services to be injected into the module.

Additional context
This would assist in implementing #8 as it requires Logger to be expanded.
