• Unifies FileSystemDataVault with other DataVaults, removes FileSystemVaultPath. VaultPaths now use file:// uris with absolute paths for the local file system.
• Allows exploring datasets in the local file system, in directories listed in the new config key datastore.localFolderWhitelist
• Note that this introduces file:// uris also in the resulting datasource-properties.jsons. Those will not be sensibly explorable by the WebknossosZarrExplorer but I guess that isn’t a use case anyway

Steps to test:

• Add a directory to config setting datastore.localFolderWhitelist
• Put dataset directory in there (or into its children/descendents)
• Explore that dataset in the Add Datasets view, prepend file:// to the absolute path (so there are then three consecutive slashes)
• Should work
• Should not work is the directory is not in the whitelist
• Other datasets with mag locators (everything that isn’t wkw) should still work (with relative path + with remote path)

TODOs:

• Unify FileSystemDataVault with other DataVaults, remove FileSystemVaultPath
• Allow exploring locally
• Add config option to whitelist directories in which webknossos may read
  • Use in datastore when reading from data vault
  • Use in webknossos when exploring
• Test that this does not break existing datasource-properties.jsons
  • with local relative path
  • with remote path

Issues:

• fixes ExploreAndAdd route: support datasets on local file system #7387

• Updated changelog
• Needs datastore update after deployment
