Provide a React NativeScript based template through the CLI

Is your feature request related to a problem? Please describe.
A user should be able to start quickly with a React NativeScript project from the CLI.

Describe the solution you'd like
tns create should be able to use a React NativeScript template to start my project from. The template should be available in the interactive prompt or through the CLI options

Describe alternatives you've considered
An alternative is to start with a React NativeScript template in the Playground, which is also going to be evaluated.

Additional context
The template to be used is proved by @shirakaba in a dedicated repository.

從 tns create 命令開始，檢查如何透過互動式提示和 CLI 選項提供範本。將預期的專案結構與連結的 react-nativescript-starter 儲存庫中的 starter template 進行比較。當使用者可以使用該範本透過 CLI 建立 React NativeScript 專案時，即表示完成。
