Icons missing in .eot version
Hi!
I tried to use your icons on my website, but the "Scopus" icon was not displaying on Firefox.
The same is true for me in [your gallery](http://jpswalsh.github.io/academicons), along with other icons (hypothesis, obp, ror, and zenodo).

<img width="737" alt="image" src="https://user-images.githubusercontent.com/1558791/100219726-a17c5c80-2f16-11eb-9e18-af2d639c70dd.png">

Getting rid of the .eot font fixed the issue, see diff below.

 .ai {
   font-family: 'Academicons';
```

As I have no way of opening the .eot font, I cannot check its contents, but the glyphs seem to be there in all the other versions.

Thanks!
