Coordinator report memory performance improvements on long bombing runs

[daveharris1]

NBomber version: 5.7.0
.NET version: 8.0

After speaking to Anton he believes the Coordinator memory usage can be be more performant when collating and producing the final reports:

The Coordinator do not keep logs in memory, it writes them on disk. The coordinator keep Realtime stats in memory which btw shouldn't be a huge problem. When JSON serialization happens for building HTML, it requires allocating a lot of RAM for long-running scenarios.

This can cause issues such as OOMKIlled on the Coordinator.

Hi @daveharris1
We added many new memory optimizations. Could you please try the latest 5.9 beta?
