DataTexture support.

[NikitaDudin]

It would be a good to have a possibility to create a textureSource directly from raw data, width and height.

const textureWidth = 1024;
const textureHeight = 1024;
const textureData = new Uint8Array(textureWidth * textureHeight * 4);
for (let i = 0; i < textureWidth * textureHeight * 4; i += 4) {
  textureData[i] = 255; // r
  textureData[i+1] = 0; // g
  textureData[i+2] = 0; // b
  textureData[i+3] = 255; // a
}
...
const textureSource = createBufferFromRawData(textureData, textureWidth, textureHeight, ...otherOptions);
