Add memoryLimit option to @poi/plugin-typescript plugin

[adamsvystun]

fork-ts-checker-webpack-plugin webpack plugin that is used by @poi/plugin-typescript has the option of setting a memory limit for the type checking process. But this option is not accessible through the plugin settings. Can it by made accessible?

This is a small change. I can submit PR if necessary.

Yes, PR welcome. We can make a tscheckerOptions option for that

btw you can modify ts-checker options in poi.config.js like this:

module.exports = {
  chainWebpack(config) {
    config.plugin('fork-ts-checker')
      .tap(([options]) => [Object.assign(options, {
        memoryLimit: 512
      })])
  }
}

It's a little verbose so exposing the option might be a good idea.

Thanks for the workaround! I submitted PR for tscheckerOptions #676.
