Verified steps

  1. Call `computeRouteMatrix` on the Routes API with arrays of `origins` and `destinations`.
  2. Use a `X-Goog-FieldMask` header to request only needed fields (e.g. `originIndex,destinationIndex,duration,distanceMeters`).
  3. Read the streamed array of route-matrix elements, each keyed by `originIndex`/`destinationIndex`.
  4. Keep the product of origins × destinations within the per-request element limit, splitting large matrices into multiple calls.
