Function fetchChunkBoundsArray

fetchChunkBoundsArray(
    location: Location<Readable>,
    arrayName: string,
    logModule: string,
    notFoundMessage: string,
): Promise<ChunkBoundsArray | null>
Open a chunk-bounds-style zarr array under location and return its contents as a Float32Array.

Returns null for the expected "array missing" case — datasets without spatial ordering legitimately omit the array — so callers can fall back to loading all elements without inspecting the error path. Other failures (corrupt zarr, network errors) also return null after a warning so the loader never blocks the scene on a degraded spatial-index probe.
Parameters
- location: Location<Readable>
  zarrita location of the parent group (the loader's node).
- arrayName: string
  Zarr array key under location ("chunk_bounds", "vertex_chunk_bounds", "segment_chunk_bounds").
- logModule: string
  Log-module label used by the loader (geometry-specific).
- notFoundMessage: string
  Friendly message logged when the array is absent.
Returns Promise<ChunkBoundsArray | null>
