Correctly calculate bounds on a rotated raster (#1422)

* Add rotated.tif to test data

import numpy as np
import rasterio
from affine import Affine

a = Affine.translation(100, 200) * Affine.rotation(30) * Affine.scale(20, -10)

with rasterio.open('rotated.tif', 'w', 'GTiff', width=10, height=15, count=1,
                   crs=None, transform=a, dtype='uint8',
                   compress='packbits') as ds:
    ds.write(np.arange(15 * 10).reshape((1, 15, 10)).astype('B'))
