Fix Overdrive + Extend Debug Info

MERGE REQUEST

MR Guidelines

Overview

This MR adds two fields to the launchedWorkerInfo, overdriveWorker and pieceIndex, which are two fields I had to add during a recent debug session. These info objects are sent alongside the download responses, so they are really quite useful to get a decent amount of information about the download process, which is why I think it makes sense to extend it.
