CSM Shader broken

• three version: 0.170.0
• @types/three version: 0.170.0
• three-stdlib version: 2.34.0

Problem description:

Creating the CSM fails with the following error: Can not resolve #include <lights_pars_begin>
The original library broke with three 157, see issue and PR, but isn't receiving updates anymore from what it looks like. Would be nice to have a working version in here, not sure if these fixes apply in the same way (original library errors in a different way).

Relevant code:

const csm = new CSM({
            maxFar: camera.far,
            cascades: 4,
            shadowMapSize: 1024,
            lightDirection: new Vector3(0, -1, 0).normalize(),
            camera: camera,
            parent: scene
});

const material = new THREE.MeshStandardMaterial(); // works with Phong and Standard materials
csm.setupMaterial(material); // must be called to pass all CSM-related uniforms to the shader

Reproduce the failure with three 0.170.0 using the CSM constructor and setupMaterial call shown in the issue. Review the CSM shader path alongside the linked upstream issue and PR, then verify that MeshStandardMaterial and Phong materials no longer fail to resolve the lights_pars_begin include.
