docs: dump comparison and split acknowledgments in the 3.13.0 post

- a dump workload in bench_all and bench_rs: each engine writes a
  document parsed beforehand, and every output must read back with
  bit-identical numbers; an optional argument selects one workload
- the post's comparison gains a write table, a throughput chart, a dump
  row for all three configurations, and the x86-64 cases it loses
- the thanks section is split into adapted code and borrowed ideas
