/**
 * Converts an Observable<IDBDatabase> stream to an Observable<IDBObjectStore> stream
 *
 * This operator checks for existing ObjectStore instances with the provided store name.
 * If there is no previous instance it creates the ObjectStore, otherwise creates a `readwrite`
 * transaction
 *
 * @example
 * const database$ = connectIndexedDb('test_db');
 * // creates an ObjectStore with key-value pairs
 * const keyValueStore$ = database$.pipe(getObjectStore('test_store'))
 * // creates an ObjectStore with autoIncrement
 * const autoIncrementStore$ = database$.pipe(getObjectStore('test_autoincrement_store', { autoIncrement: true }))
 *
 * // subscribing to the observable will create the database and the store
 * keyValueStore$.subscribe({
 *   next: (db: IDBObjectStore) => console.log(store.name),
 *   error: (e) => console.error(e),
 *   complete: () => console.warn('database deleted')
 * });
 *
 * autoIncrementStore$.subscribe({
 *   next: (db: IDBObjectStore) => console.log(store.name),
 *   error: (e) => console.error(e),
 *   complete: () => console.warn('database deleted')
 * })
 *
 * @remarks Completes when the source database gets deleted.
 * @param name
 * @param options - IDBObjectStoreParameters
 *
 * @returns Observable<IDBObjectStore>
