Rebuild a fits manifest from an HSC data directory.

- Added a new verb rebuild_manifest
- When run with the HSC dataset class this verb will:
  0) Scan the data directory and ingest HSC cutout files
  1) Read in the original catalog file configured for download for metadata
  2) Write out rebuilt_manifest.fits in the data directory

- Fixed up config resolution so that fibad_config.toml in the cwd
  works again for CLI invocations.
