Allow recompute via `_make_file` func

[CBroz1]

Description

This PR adds the ability to recompute when fetching a non-existent file from v1.SpikeSortingRecording, adding some infrastructure to support expanding this tool in the future. To facilitate this, I add ...

• A standard of a _make_file func that other tables can implement in the future.

• An imperfect NWB hashing tool

  • Chunking the byte stream doesn't work because replacing values impacts checksums (thanks Ryan!)
  • Currently, I look at the first 4k rows of a dataset
  • Problematic fields for us include values below this threshold, but we would need to change for other tables
    • general/experimenter
    • general/extracellular_ephys/electrodes/filtering
    • general/extracellular_ephys/electrodes/group
    • general/extracellular_ephys/electrodes/location
    • intervals/epochs/tags

• Tests for round-trip file deletion, then calling fetch_nwb
