Easy way to view Qastle for a func_adl query

[BenGalewsky]

As a serviceX developer I want to be able to generate the qastle for a valid func_adl selection so I can run transformers with Postman

For development of the core service it is sometimes necessary to bypass the servicex_frontend library and directly hit the endpoints with Postman or Curl. It is very hard to figure out how to get a currently valid qastle query for this.
