SASS mixins are not available
Hi @jeerbl , thanks for your work on webfonts-loader - this does exactly what I was looking for when moving my team from a proprietary svg-to-font solution. I succeeded in generating the fonts and the CSS, but when it comes to SASS, I failed. I created a minimal reproducer that works fine with CSS, can be switched to SASS by removing 3 comments, and reproduces my issue.
I would be glad for any input on that I'm doing wrong, or whether the issue is caused by changes in SASS (deprecation of @import, ...)

The producer is here: https://github.com/mephinet/webfonts-loader-reproducer
The readme lists the steps to show that CSS works and to reproduce the SASS issue.
I'm happy for any input!
