Make rendering calls asynchronous (in a new Thread)

[KevinHaendel]

Currently, the native rendering processes in this package are executed synchronously on the main thread, which can cause performance issues and potential UI freezes, especially when swiping through multiple pages using the ListView.builder example from the README file. Is it possible to make the rendering processes asynchronous and execute them in a separate thread for at least both Android and iOS? I think it is possible to return the rendering result to the method channel from the new thread, so it should be no big deal to change the source code for this, or am I missing something?
