LUCENE-10508: Fix error for rectangles with an extent close to 180 degrees
(#824)
This commit introduces a GeoWideRectangle.MIN_WIDE_EXTENT that takes into
account the angular resolution
in order to build a GeoWideRectangle.

> I hit a failure when trying to build a GeoArea using the GeoAreaFactory. The
> issue seems to happen when you have an almost degenerated minLatitude and
> maxLatitude and you are close to the poles. Then you might hit the following
> exception"
> {code}
> java.lang.IllegalArgumentException: Cannot determine sidedness because check
> point is on plane.

> minX, maxX));
