Matrix effect in terminal with FOSS icons

Hi, I was playing with rusty-rain when I decided that it was a good idea to make a custom FOSS effect. For this I made a change in “sibling” project ezemoji PR and with a small local change in rusty-rain I got it. All icons are from Nerd Fonts, so if you know of some FOSS icon is missing let me know to add it in the PR, =).
