GeoTessera Tile Client

Fetch, dequantize, and mosaic GeoTessera embedding tiles.

GeoTessera provides satellite imagery embeddings as a tiled grid of quantized numpy arrays. This library handles the tile arithmetic, downloads the relevant tiles for a bounding box, dequantizes them using per-tile scale factors, and stitches the results into a single embedding matrix.

The I/O layer is parameterised so the same code works in native OCaml and in the browser (via tessera-geotessera-jsoo).
