CI fails because this depends on the two PR linked through the references. Not sure if there's a nice way to run CI for such interdependent PRs. |

This PR allows to watch downloads. It adds
watchDownloadsandunwatchDownloadsmethods to the hypercore service. If watching downloads,onDownloadis called towards the client for each downloaded block. Only theseqis transferred, not the full block. Download events are disabled by default, to skip the overhead for clients that don't need them.This is a part of #2 and a step towards running kappa-style apps on top of hyperspace, especially for indexing sparsely synced hypercores in live mode.
Instead of adding
watchDownloadsandunwatchDownloadsmethods I was also considering of adding a singleoptionsmethod with aOptionsRequest { bool watchDownloads = 1 }. When/if other session options came along that could make this more straightforward instead of adding getters and setters for each option - not sure though.
