@zarrita/indexing

• Operates on core zarr.Array for advanced indexing and slicing.
• Offers an ergonomic API familiar to Zarr/numpy users.
• Returns objects with strided TypedArrays

const region = await get(arr, [null, null]);
// {
//   data: Uint16Array([ 1, 2, 3, 4]),
//   shape: [2, 2],
//   stride: [2, 1],
// }
