Feature request: using ufo provider in diff-mode

[simonmandlik]

Feature description

Hi, is it possible to use ufo providers even in diff-mode?

I'm using https://github.com/sindrets/diffview.nvim and have seen e.g. #57 (comment). But these settings just turn off initial folding altogether.

Is it somehow possible to still use the ufo providers here as in other buffers?
