[Proposal] Nest time_ and network_track_ and other <type>_ within results

[CodyCBakerPhD]

Currently, in reference to a file like https://github.com/NeurodataWithoutBorders/nwb_benchmarks/blob/main/results/results_timestamp-2024-02-20-01-07-39_machine-e9c0f1370ec8dc3640d91c7d0f381a6d61bd9a46_environment-2d1c68a2c7de02ab2c200e448b250bee5e46f212.json

we have separate JSON entries per benchmarks like

network_tracking_remote_file_reading.FsspecNoCacheDirectFileReadBenchmark.track_network_activity_during_read

and

time_remote_slicing.FsspecNoCacheContinuousSliceBenchmark.time_slice

which functionally have the same setup, and test the same functionality using different methods

It was proposed that it might be more readable / nicer to relate similar tracking results to each other in the results files

I am unsure if it would be better to keep a flat results structure and then add nicer summaries on top of that (which could easily aggregate related fields such as this), or if we do want the results files themselves to be more human-understandable at a glance

One such aggregation could look like

"FsspecNoCacheDirectFileReadBenchmark": {
  "track_network_activity_during_read": [...],
  "time_slice": [...]
}
