Non colored file icons

[Diaoul]

Is your feature request related to a problem? Please describe.
I find colored icons too distracting in nvim-tree.

Describe the solution you'd like
The ability to show the icon in the same color as the text with an option or the ability to customize it entirely (like the folder icons)

feline.nvim has a colored_icon option that allows to get the icon without the color.

Here is an example with exa that seems to use non-colored icons by default as well (and probably another set of icons):
exa -al --icons

Describe alternatives you've considered
Using NvimTreeFileIcon highlight group does not work.

Additional context
🤷

Looks like we forgot to add the note that the HL group doesn't apply to web-devicons: #1131

Changing web-devicons colours can be done: take a look at the conversation in the PR and you should be able to put something together. PRs are always welcome :)

Edit: both resolved in #1175

Wow that was fast and looks like a clean fix in the PR. Thanks a lot 👍

I would be grateful if you could test this branch:

#1172-non-coloured-webdev-file-icons

PR is still open, so best to catch issues now.
