Idl-serial can convert IDL to JSON with less codes.

I've noticed that the typedef parser feature has been in the TODO list for a long time. I'm looking forward to this feature and hope it can come out in the near future.

Hey @OdyWayne , could you please assign this issue to me?

[StargazerWayne]

Yes, of course. But since this is the feature we are about to working on, we would expect it to be done as soon as possible.
