/**
 * Creates and manages an object URL for the provided `Blob` or `MediaSource`.
 *
 * The hook:
 * - creates an object URL for the current object
 * - updates the URL when the object changes
 * - revokes the previous URL asynchronously to avoid revoking it while it may still be in use
 * - revokes the current URL on unmounting to prevent memory leaks
 *
 * This hook returns `null` when no object is provided.
 *
 * @param obj - Source object used to create an object URL.
 *
 * @returns Object URL for the provided object, or `null` when `obj` is not defined.
 *
 * @example
 * ```tsx
 * const objectUrl = useObjectUrl(mediaFileData);
 *
 * return objectUrl ? <img src={objectUrl} alt="Preview" /> : null;
 * ```
