As noticed in #249, we weren't handling unaligned edge tiles correctly. This PR ensures we render edge tiles correctly by implementing support for non-boundless reads. ### Change list - `GeoTIFF.fetch_tile` gets a new parameter `boundless: boolean` that defaults to `true` (to match `async-geotiff` in Python), but we set to `false` here for cleaner rendering. <img width="605" height="656" alt="image" src="https://github.com/user-attachments/assets/3d36efe7-59a9-42d7-9f0f-d86ab2a4ad23" />

With the switch to @cogeotiff/core, we now handle JPEG decoding via canvas, which automatically handles YCbCr -> RGB before it gets to us, so we don't have to do it again on the GPU.
