Re-add some events that were removed before

[UniquePanda]

After #1 some events were changed so that they are only used internally.
As they were available to the outside (via .on() on the resumable object) before, it doesn't really make sense to only use them internally now. The internal handlers in resumable.ts and resumableFile.ts could just fire these events after handling.

The affected events are:

• fileError
• chunkingStart
• chunkingProgress
• chunkingComplete
• catchAll

Additionally:
Just fire all events from all chunks and all files also from the main resumable object.
This can be especially helpful in debugging scenarios.
