Refactor CylinderSector to allow angles more than 180°

[nplinden]

Description

A proposition for change solving issue #3293, that causes the CylinderSector to have an angle limit of 180° rather than 360°.

Fixes

The existing CylinderSector class is renamed to _HalfCylinderSector, the _ prefix indicating that it is for internal use only.
A new CynlinderSector class is created, and is a composite surface made up of two _HalfCylinderSector like so:

This naturally doubles the angle limit to from 180° to 360°.

Pros: This fixes requires very little additionnal code and no additionnal trig/boolean algebra, with no API change
Cons: This add an unecessary middle plane if the angle is less than 180°
