Unform methods for result access
Is there a set of uniform methods for accessing the results of a query? Could be good to have something like the ones available in sqlite adapters
- .get() to get the first result Promise<T | null>
- .all() to get Promise<Array<T>>
- .iter() - can have a default implementation based on iterating over an array of all the elements, but could also support a memory-saving AsyncIterable for adapters that can do streaming
