Support [hash] in spriteFilename when extracting (Feature Request)

[wanecek]

To handle caching of the sprite, it would be useful to be able to include a [hash] in the filename of the sprite.

What would it take to implement this? How can I assist?

@wanecek it already supported in svg-sprite-loader@beta as [spritehash], e.g:

module.exports = {
  module: {
    rules: [
      {
        test: /\.svg$/,
        loader: 'svg-sprite-loader',
        options: {
          spriteFilename: '[chunkname].[spritehash].svg'
          // or as a part of query param
          // spriteFilename: '[chunkname].svg?[spritehash]'
        }
      }
    ]
  }
}

Please note: in 2.1.0 it will be renamed to [hash]
