Also added more metrics to keep track of . Sample test output:

8MiB block size, 2MB ingresses:

     Success rate: 100.0%
     Block rate: 1.90 blocks/s
     Throughput: 8.99 MiB/s, 4.71 messages/s
     Average time to receive a rank 0 block: 0.311s
     Avarage E2E ingress message latency: 3.43s
     Avarage time to create a block payload: 0.025s
     Avarage time to validate a block payload: 0.016s
     Avarage time to assemble a block proposal: 0.043s

4MiB block size, 2MB ingresses:

     Success rate: 100.0%
     Block rate: 2.21 blocks/s
     Throughput: 6.50 MiB/s, 3.40 messages/s
     Average time to receive a rank 0 block: 0.251s
     Avarage E2E ingress message latency: 9.49s
