Following from #9330, we need a tool (which could be the same as the one developed in #9330, or could be separate) to scan through the blockchain data and compute transaction latency statistics for each throughput rate based on the timestamp in the transaction compared to the timestamp of the block in which it was included.

The following statistics must be computed for each throughput rate:

• Minimum latency
• Maximum latency
• Average latency
• Latency standard deviation

The output must be in a relatively easily machine-legible format, e.g. CSV, clearly showing throughput vs. each of the above latency statistics.
