/**
* Containment test, whether tetrahedron defined by A,B,C,D contains point E or not
* Implemented using planar tests on each of side of the tetrahedron
*
* NOTE: similar to https://gitlab.onelab.info/gmsh/gmsh/-/blob/master/contrib/hxt/tetMesh/src/HXTSPR.c
* We skip identity checks and bounding box checks. Identity is a waste of time when building tetrahedral mesh,
* since each inserted point will be new to the mesh, box checks are not relevant as we don't track those
*
* @param {number[]} points
* @param {number} a
* @param {number} b
* @param {number} c
* @param {number} d
* @param {number} e
* @returns {boolean}
