Read one logical patch’s array over half-open positional windows.

windows holds a (start, stop) sample range for each axis of the returned array, in order, as array[start:stop, ...] would; an entry of None, or an axis left off the end, is returned whole; the framework really does pass None, so an implementer must take it. The array has the axis order, shape, and dtype declared by get_metadata, including format-specific layout and scaling. key names the array: the logical patch of a multi-patch resource, or a path inside the resource. Readers which cannot slice storage decode and then slice.
