Can we report a CMAF chunk a response? #147

LL-DASH allows long-running responses spanning multiple CMAF chunks. It is sometimes useful to report parameters (buffer, ttfb/ttlb, etc) per chunk. I don't think this is supported now, as we only consider full responses. Proposal: enable response mode on chunk arrival (as opposed to completion) and enable a ps key indicating either (a) the number of a partial segment (for LL-HLS / L3D) or (b) number of CMAF chunk in a single request.

But you can quite often not even detect chunk boundaries in DASH segments. They are transparently handed to MSE.
