Support for filters on Dynamodb GetItem

[KodiVerse]

It would be great to add filtering functionality to getItem as it is done in query. This will allow us to do more complicated filters when getting a single item from dynamodb. This would remove the need for complicated filter logic after the item is return.

ex...

dy('order').getItem(key, {
  filters: [
    { attr: 'deleted', eq: 0 },
    { attr: 'itemIds', contains: 123 }
  ],
});
