basic usage

const worker = createWorker();

const result = await worker.createTile({
// url to a geotiff
url: "https://storage.googleapis.com/pdd-stac/disasters/hurricane-harvey/0831/20170831_172754_101c_3b_Visual.tif",

// bounding box of tile in format [xmin, ymin, xmax, ymax]
bbox: [-95.976562, 29.535232, -95.888671, 29.611673]
});

const worker = createWorker();

// untyped - use only untyped arrays
