Sucrase support

[iki]

Is there any way how the hot loader could work directly with sucrase? Currently it requires the slow babel step to transpile typescript into es6 (alangpierce/sucrase#228):

 // Load TypeScript (.ts, .tsx).
      {
        test: /\.tsx?$/,
        use: [
          ...(isDevServer
            ? [
                {
                  loader: 'babel-loader',
                  options: {
                    babelrc: false,
                    plugins: ['react-hot-loader/babel'],
                  },
                },
              ]
            : []),
          ...(targetES6
            ? [
                {
                  loader: '@sucrase/webpack-loader',
                  options: {
                    transforms: ['imports', 'jsx', 'typescript'],
                  },
                },
              ]
            : [{ loader: 'ts-loader', options: { configFile: paths.tsConfig } }]),
        ],
      },

So, it's up Sucrase.
