Examples: radialSegments -> radiusSegments

[wstomv]

In

pythreejs/examples/Geometries.ipynb

Line 173 in 952ab13

" radialSegments=6, \n",

and other places, radialSegments appears, but this should be radiusSegments.

Thanks for the report! There is definitely an error here, but the three.js docs/code should be considered the source of truth here. I'll add this to #253 shortly!
