/**
 * File Indexer Service for indexing asset files.
 *
 * Opening and parsing a large collection of asset files inside a library can take a lot of time.
 * To reduce the time it takes the files are indexed.
 *
 * - Index files are created for each blend file in the asset library, even when the blend file
 *   doesn't contain any assets.
 * - Indexes are stored in an persistent cache folder (`BKE_appdir_folder_caches` +
 *   `asset_library_indexes/{asset_library_dir}/{asset_index_file.json}`).
 * - The content of the indexes are used when:
 *   - Index exists and can be opened
 *   - Last modification date is earlier than the file it represents.
 *   - The index file version is the latest.
 * - Blend files without any assets can be determined by the size of the index file for some
 *   additional performance.
