Implement support for SVG/PNG icon sets

[odebroqueville]

Problem

Right now the looks are a bit disappointing and there's no default config file to handle different common file types, like PDF, Word, Excel, JS, HTML, CSS, etc...

Description

I really like the Material Design icons used in VS Code. I feel it would make a big difference if we could have them in the terminal (I'm thinking Warp preferably or iTerm2).

Alternatives

I've tried exa which is now deprecated and has been replaced with eza. It has an --icons argument which displays icons next to files and folders. However, I find that it's not quite as polished as pls, especially the --long view. I'd be interested to know how they display the icons though. Are they just using a nerd font or is it something else?

Additional information

Warp is being actively developed, so maybe they could make changes so that SVG icons could be used in their terminal. However, I honestly don't know if this issue feasible, because I remember that terminals are text based.

P.S. On a side note, it would be nice to have a directory where users could share their config files (.pls.yml).
