Investigating the logs from a recent long run, I found a bottleneck in sequential processing of events from DX. PR hyperledger/firefly#653 addresses the big inefficiency that showed up in the long run test, and made the issue very evident in the logs.
However, for higher throughput it's obvious to me looking at this code that we need parallelism and batching in how we process blob confirmation messages in particular.
This means we need to process multiple DX events in parallel, and currently the FFDX API contract doesn't support that. You have to ack one-by-one.
This PR updates the HTTPS data exchange to add a simple readahead support, updating the ack contract so you have to specify which event you're acking.
