Right hand rule for polygons + outdated NPM

[oyvindi]

The current version is not handling RHR correctly, but seems like @rurban made a fix (see #81)

According to RFC 7946, exterior rings are counter-clockwise, and opposite for interiors.

Would be nice to have this merged to master, and publish a new NPM (the latest version there is 2.0.0)

Here is a sample MultiPolygon that should be correct, but fails validation:

@oyvindi confirmed. Thanks for the example. I will add it to the test suite.
