feat: More auto-unfold options

Browse Source 
Option to auto unfold when there is only N root nodes in outline.

Defaults to 1, meaning if there is only one 'root' parent, it should
always be unfolded.

This is useful if the entire file is a single function or a single
'return'.

The old auto_unfold_hover option **still works as expected**.
