expand_all to expand all folders to make live_filter more awesome

[dbarrosop]

Is your feature request related to a problem? Please describe.

The new feature "live filter" is pretty awesome but it is not very usable due to two reasons:

1. It only searches expanded folders (I actually think this is desirable).
2. There is no shortcut for expanding all folders

Describe the solution you'd like

I think it'd make sense to add a shortcut to expand all folders. There is already one to colapse_all but not to do the opposite.

Describe alternatives you've considered

Known limitation. It needs a recursive filesystem search: #1056 (comment)

It can be done.

You mean the expand_all or the ability to search everywhere? Just to be clear, I think the current behavior makes sense (only search in expanded folders). I don't expect to be using this plugin to actually search in my entire worktree, for that I think telescope+fzf makes more sense, I expect to be using this though to narrow down the list of files I want to see in a set of folders while working on a feature or bug (kinda like a "focus" mode).

What I am arguing for in this issue is to have a shortcut to expand all folders. Right now this plugin has W : collapse_all so having the opposite could help with this. This way if someone wants to filter in the entire tree they can expand_all first and then trigger live_filter.

expand_all has been asked already, i'm going to implement it soon i think, it's not too hard. Although this could be very slow if you run the command on the home folder or the / folder :)
