Use read_block when reading slices of the entire arrays

[genematx]

Use read_block methods for reading slices of array data.

Description

Motivation and Context

When reading slices of big arrays, Tiled by default calls the .read(slice=...) method, which causes databroker to fetch data for the entire array, event hough most of it may be discarded during slicing. These changes allow the server to only fetch necessary chunks.

How Has This Been Tested?

Utility functions are tested in Tiled. Full workflow is tested in a dev set-up with mounted MongoDB.

Oh, better bump minimum tiled version first!
