[Feature]: support of `mini.icons`

[mathjiajia]

Problem

Currently only support nvim-web-devicons
it will be great to support mini.icons as well

ref: https://github.com/echasnovski/mini.icons

Expected behavior

display the correct icon/hl when mini.icons is available`

I think you can use MiniIcons.mock_nvim_web_devicons(), as mentioned in their doc.

why not to have a ‘native’ support?
