Add astro-iconset as an alternative Astro SVG icon integration

[sudeep2003]

Hi! astro-iconset, an SVG icon integration
for Astro that builds on top of Iconify.

npm: https://www.npmjs.com/package/astro-iconset
Docs: https://astro-iconset.wingflows.com
GitHub: https://github.com/sudeep2003/astro-iconset

It supports all Iconify icon sets just like astro-icon, but adds:

• Named directory prefixes for local icons (brand:logo, ui:menu)
• ?icon imports for one-off SVGs without a shared directory
• Framework island support (React, Vue, Svelte, Preact, Solid)
• Sprite deduplication and zero browser runtime

Would it be possible to add astro-iconset to the Astro usage docs
alongside astro-icon? Happy to open a PR if you can point me to
the right place in the docs to add it.

Thank you!

Looks good, I'll add it.

One note though: one of features of your package is SVGO. Don't use it for Iconify icon sets. Icon sets in Iconify are already optimised, so it is not needed. SVGO has a lot of bugs that appear in certain conditions (most notable: zero length shapes with stroke, breaking shapes in animated icons), so blindly using SVGO without testing output might break icons.
