**Is your feature request related to a problem? Please describe.**
I recently noticed there's a GitHub topic, [Operator Mono](https://github.com/topics/operator-mono), for repos about a very nice font for coding. (https://github.com/kiliman/operator-mono-lig is currently the most popular of these.) I was wondering if you might accept a PR to include this font along with the others that are included in this project.

**Describe the solution you'd like**
Operator Mono is included along with the other fonts in this collection.

**Describe alternatives you've considered**
An alternative is to obtain this font from other sources. However, including it within nerdfonts would allow e.g. Nix users to obtain it via [the "nerdfonts" Nix package](https://search.nixos.org/packages?show=nerdfonts), which would make it easier to obtain for Nix users (and similarly for other package ecosystems).

**Additional context**
Thanks for your work on this project!
