 * Custom LightingEffect for kepler.gl.

 * Extends deck.gl's LightingEffect with:
 * - A patched shadow module with `outputUniformShadow` for uniform shadow
 *   during nighttime (avoids partial shadows from below).
 * - getShaderModuleProps override that always provides dummyShadowMap
 *   to prevent "Bad texture binding" errors when shadows are disabled.
