Masking error for complex multipolygon cutlines with holes

See original GitHub issue

rio-tiler version: rio-tiler==2.0.0rc4

Recreate:

from rio_tiler.io import COGReader
import matplotlib.pyplot as plt


feature = ... # huge multipolygon I'll attach separately

with COGReader('https://rio-tiler-dev.s3.amazonaws.com/data/eu_webAligned_256pxWEBP.tif') as cog:
    data, mask = cog.feature(feature['geometry'])

plt.imshow(mask)
plt.show()

rio-tiler-mask

Tried the .buffer(0) trick as well with no change to the result. Geometry returns True for is_valid
