Library and CLI tool for 3D Gaussian splat format conversion and transformation

/**
 * Binned rasterize shader. Each workgroup handles one tile and only walks
 * the splats that have been pre-binned into it (tile-bin pre-pass on CPU
 * or GPU). Replaces the "walk all splats per pixel" loop in a non-binned
 * rasterizer with "walk this tile's slice", which is the asymptotic
 * fix for performance at high splat counts.
 *
 * The slice is stored in two buffers:
 *   - `tileOffsets[T + 1]` — exclusive prefix sum: tile T's slice is
 *     `tileData[tileOffsets[T] .. tileOffsets[T + 1])`.
 *   - `tileData[]` — splat indices, grouped by tile, depth-sorted within
 *     each tile (the orchestrator's CPU pre-sort + stable per-splat
 *     binning produces this layout for free).
 *
 * Projection-mode variation: `PROJECTION_EQUIRECT` wraps the per-pixel
 * `dx = px - splat.x` into `[-W/2, W/2]` so a tile on the opposite side
 * of the ±π longitude seam evaluates against the splat's nearer copy.
 * Without the flag the raw delta is used.
 *
 * @returns WGSL source for the binned-rasterize compute shader.
