Minimize dependencies

We can lighten the library up a bit.

Update _build_bbox to not need NumPy. I'm guessing a for loop over the bboxes will be roughly as fast as creating an ndarray and doing the min / max, at least for moderately sized datasets. Profile and drop NumPy if it's not much slower. https://github.com/stac-utils/stac-vrt/blob/e881e8c30a1f14032d147577b516a50762820548/stac_vrt.py#L38-L41
Replace all uses of rasterio.coords.BoundingBox with a tuple (or make our own BoundingBox namedtuple).
Replace rasterio.warp.transform_bounds with... something. Maybe in pyproj. If this is hard then I'm fine with just depending on rasterio.

Rasterio depends on numpy anyways, so IMO removing numpy for the sake of minimizing dependencies isn't too important unless you also plan to remove rasterio. https://github.com/mapbox/rasterio/blob/0a52d52b0c19094cd906c25fe3c23ddb48ee1f48/setup.py#L260
