Font Awesome 7 support

[sebastianst]

It seems the awesome6 icon setting doesn't support the new Awesome 7 fonts. Half of the icons are broken.

This is related to #2181 which suggests to install package otf-font-awesome on Arch Linux - which I did, so now half the icons look as before, but the other half are broken (like the battery or Wifi symbols).

@sebastianst I was going through the icons, so I can make the new icon set for Font Awesome 7 (because I had the same problem) and the icons you mentioned are supported in Font Awesome 7.

In my case I still had FA6 used in sway config, when I updated the font name the network icons rendered correctly (I am using otf-font-awesome on Arch Linux as well). The icons that worked are not actually coming from the Font Awesome, but are standard Unicode emojis.

So can we confirm that https://github.com/greshake/i3status-rust/blob/master/files/icons/awesome6.toml is fully compatible with FA v7, or do we need to add an awesome7.toml file as well? I do not have time to investigate codepoint changes etc so help would be appreciated.

@ammgws I will go through all the icons in the file to make sure. Though I think having a awesome7 file (be it regular file or symlink to awesome6) would be good idea either way.
