\brief Resolve a logical index to a ChunkLocation. The returned ChunkLocation contains the chunk index and the within-chunk index equivalent to the logical index. \pre `index >= 0` \post `location.chunk_index` in `[0, chunks.size()]` \param index The logical index to resolve \return ChunkLocation with a valid chunk_index if index is within bounds, or with `chunk_index == chunks.size()` if logica
