Adding Font Ligatures

[Tygo-van-den-Hurk]

Is your feature request related to a problem? Please describe.
I use Open Dyslexic everywhere, my terminal, code editor, documents, even my web browser forces it on each site. However there is one thing that is a bit of a shame: the font doesn't support Font Ligatures.

First I thought they didn't just patch the font correctly, however when doing some extra research for the issue was gonna submit at Nerd Fonts, I found out thanks to this issue that such ligatures must be added upstream. Which is why I'm submitting this issue.

Describe the solution you'd like
I'd like to see font ligatures being added to the font.

Describe alternatives you've considered
I've considered asking nerd fonts to patch them with font ligatures but found out thanks to that issue that they can't/won't. Font Ligatures can only be added upstream. I don't know enough about fonts at all to be able to become a middle man upstream source myself.

Additional context: What are Font ligatures?
Font ligatures are special glyphs that combine two or more characters into a single symbol, typically used in programming fonts to improve the readability of code. They replace common character combinations, such as != or ->.

The problem with including it from the start is there would be valid reasons for people wanting it without. I didn't have a good process for doing both at the time.

I plan a release on 1/10, and If that goes well I'll be back to working on monospace and will plan to include that.
