<noscript> support
I try to build my websites as compatible as possible for those who don't use client-side javascript;

I could embed all the SVGs I intend to use independently, but this is a major time consumer.

Feather Icons implements using an svg "sprite sheet" which allows me to embed icons as so:
```
<svg
  width="24"
  height="24"
  fill="none"
  stroke="currentColor"
  stroke-width="2"
  stroke-linecap="round"
  stroke-linejoin="round"
>
  <use href="path/to/feather-sprite.svg#circle"/>
</svg>
```

As far as I can tell, phosphor doesn't have a similar SVG available for use - just each icon as an individual file.

I'm curious if such an implementation could be added - or does the Phosphor team have another, more preferred way of embedding these icons script-less? Thanks.
