 * Hook for listening to document events.
 * The hook will automatically subscribe to the document room, and unsubscribe when the component unmounts.
 * The hook listens to the following events:
 * - doc_update: This is triggered when the document is updated. The callback function will receive the updated document.
 * - doc_viewers: This is triggered when the list of viewers of the document changes. The hook will update the viewers state with the list of viewers.
 *
 * @param doctype Name of the doctype
 * @param docname Name of the document
 * @param emitOpenCloseEventsOnMount [Optional] If true, the hook will emit doc_open and doc_close events on mount and unmount respectively. Defaults to true.
 * @param onUpdateCallback Function to be called when the document is updated. It is recommended to memoize this function.
 *
 * @returns Returns an object with the following properties: viewers - array of userID's, emitDocOpen - function to emit doc_open event, emitDocClose - function to emit doc_close event
 *
 * @example
 *
 * const { viewers, emitDocOpen, emitDocClose } = useFrappeDocumentEventListener('DocType', 'name', (data) => {
