5.1.0 Burger icon mixins support CSS vars

Breaking Change

The burger() and burger-to-cross() mixins now use CSS variables instead of Sass vars:

.icon {
  // Required vars
  --burger-icon-gutter: 6px;
  --burger-icon-stroke-width: 2px;
  --burger-icon-width: 30px;
  // Optional vars, defaults shown
  // --burger-icon-color: currentColor;
  // --burger-icon-radius: 0;
  // --burger-icon-speed: 200ms;
  // --burger-icon-cross-angle: 45deg;
  // --burger-icon-cross-color: currentColor;
  @include burger;

  &.is-active {
    @include burger-to-cross;
  }
}

4.1.1 Fix logging errors in helper functions

fs-to-length() and fs-to-number() were copied from this post originally . A year later the author posted an updated version, which I also copied, but I didn’t notice it switched to using Compass for logging instead of the native Sass @warn.

- @warn "Unknown unit `#{$unit}`.";
+ $_: log('Invalid unit `#{$unit}`.');

I think this never caused any issues previously since both functions are rarely used—and when they are it’s unlikely a dev would use them incorrectly. However, the latest version of Sass started complaining about the syntax which led me to realize it used non-Sass code.
