What algorithms should we support? AIMD and Cubic?

I wonder if window size control should be made an independent module and separated from fetcher logic. It might be useful to other future apps as well.

For getting started, I'll suggest whatever has lower complexity (my recollection is not very good)

I have created a draft PR (actually through an accidental touch) #131 , which contains some basic window control/signalling functionalities. LMK if that's a good start
