up to date map for font awesome 6

[philippkeller]

I wanted to go for font awesome 6 but saw that this repo is based on version 5.

I ended up not using this repo but instead putting a map directly in my project (one less dependency), if you want to do the same, then you could use this gist as a starting point: https://gist.github.com/philippkeller/2e017e43ff4d9472cba655031698abaa
