fold function

[WebKenth]

Sometimes i like to add alot of debugging ray() requests with labels

however whenever i ray a big object it auto folds to first nesting level.

it would be nice if we could control folding so they would land on newlines and then we can unfold them at our own pace

was thinking in simple terms like:

ray($data)->fold()

likewise the opposite could also be added

ray($data)->unfold($nesting_level)
