Remove support for `eot`, `otf`, `woff`, and update mime type for `woff2`

Related to Issue

Fixes #359

Description

With the wide support of woff2 in modern browsers, there is no need to continue using woff. While I was at it, I went ahead and removed eot and otf support as well. woff2 alone is sufficient for most projects but depending on your site user base, you may want to add back in woff support (especially if Internet Explorer is still in use, despite it's support end-of-life by Microsoft).
