/**
 * Creates an LRU (Least Recently Used) cache Handler.
 *
 * This function initializes an LRU cache handler for managing cache operations.
 * It allows setting a maximum number of items and maximum item size in bytes.
 * The handler includes methods to get and set cache values.
 * Revalidation is handled by the `CacheHandler` class.
 *
 * @param options - The configuration options for the LRU cache handler. See {@link LruCacheOptions}.
 *
 * @returns An object representing the cache, with methods for cache operations.
 *
 * @example
 * ```js
 * const lruHandler = createLruHandler({
 *   maxItemsNumber: 10000, // 10000 items
 *   maxItemSizeBytes: 1024 * 1024 * 500, // 500 MB
 * });
 * ```
 *
 * @remarks
 * - Use this Handler as a fallback for any remote store Handler.
