Schema tests

Structure:

- context:
    ...
  rule: rules.X.Y.Z
  does: pass
- context:
    ...
  rule: rules.X.Y.Z
  does: notapply
- context:
    ...
  rule: rules.X.Y.Z
  does: fail

Two styles of test: File-based and mock context-based

sidecars, tabular_data, checks, files, errors

- rule: rules.checks.micr.PixelSizeInconsistent
  does: pass # fail, does-not-apply
  files:
    - data_file: bids-examples/micr_SPIM/sub-01/micr/sub-01_sample-A_stain-LFB_chunk-03_SPIM.ome.tif
    - sidecars:
      - bids-examples/micr_SPIM/sub-01/micr/sub-01_sample-A_stain-LFB_chunk-03_SPIM.json
- rule: rules.checks.micr.PixelSizeInconsistent
  does: pass # fail, does-not-apply
  context:
