Command to fold everything under a level? analogous to hs-hide-level

[nasseralkmim]

Is there such command?

Something like #14? 🤔

It is a similar idea, actually cycling would be even better.
The hs-hide-level hides everything below the current level.
If you are at a function level, you hide if-statements, for example.
At the module level, it hides the functions.
