Generate Puppet Schema from TypeScript Automatically

[huan]

As mentioned by @suntong from #11 (comment):

"Convert TypeScript types to GO" right? -- https://app.quicktype.io/#l=Go
Meaning that we should make TypeScript type definitions as individual files, separate their implementations from them. So whenever the types get changed, the Go/Java/Python type definition files can be changed semi-automatically as well.

I believe it will be great if we can have a good design to use the automatic generation from this tool because the wechaty-puppet will be changed in the future frequently, and it will be great if we can be prepared and leave all the work to the machine.

Update: we can import all the wechaty-puppet schemas from the go-grpc.

Python Wechaty team are using this strategy, and I'd like to suggest our Go team to try it if the Python team proved it works well.
