[FEATURE] TS Types of generated JSON doc

[imike57]

Hello,

I'm using compodoc with json export to implement the doc in an external application.

But the JSON do not necessarily include all use case. That's why I'm looking for a TS Types of the JSON export which could be a great help.

I tried to search around the compodoc source, but I see nothing about it.

Maybe it's something that existe already ?
