[Feature Request] Add custom keybind option for 'Next/Previous Recipe Category'

[qyurila]

I really hope there is a way to customize the 'Next/Previous Recipe Category' keybinds. JEI has the customizability and I can't live in a world where they aren't being a and d.

I actually don't mind the fixed keybinds of 'Next/Previous Recipe' being mouse wheels, but it also would be a good place to add custom keybind options.

This seems useful, I'll add it
