Does your feature request involve difficulty completing a task? Please describe.
I am developing/maintaining a fork of Aard2 which is not really maintained anymore
So i had to change the app id for my new app.

Consequently it is not working with koreader.

Describe the solution you'd like
Add support for aard2.lookup intent (like OnionViewer is doing) that way it does not depend on the aard2 package id.

Describe alternatives you've considered
The other solution would be to add my app id to koreader but it does not seem like the right solution. Supporting aard2.lookup would make it work with any aard2 fork (or even any app supporting aard2.lookup intent)
