Add some new packing and unpacking expression functions corresponding to the WGSL functions `pack4x8snorm`, `pack4x8unorm`, and their unpack equivalent. Those are very commonly used to convert between low definition `u32` color 0xAABBGGRR and high-definition `vec4<f32>` color. Update the `billboard.rs` example to use those new expressions to store a per-particle color initialized randomly on spawn. Bug: #259
