Support for class component.

Hi @Amour1688,

first of all thank you very much for taking the time to create vue-jsx-hot-loader.
I was testing today vue-jsx-hot-loader in new Vue app with jsx/tsx and the loader worked really really nice. Thanks again :)

My question is, can we make the vue-jsx-hot-loader, to work with vuejs/vue-class-component?
