Suggestion: mount optimized icons

[rhcarvalho]

I was looking at what gets published to NPM, and seems that their build script takes input from src and output to optimize, then copying the result to top-level directories and releasing that.

https://github.com/tailwindlabs/heroicons/blob/eee05eb77af6cdedfb97f128d1998773fc984b28/package.json#L17-L19

In my project I changed the mount point to use the optimized version of the icons:

  [[module.imports]]
    path="github.com/tailwindlabs/heroicons"
  [[module.imports.mounts]]
    source = "optimized"
    target = "assets/svg/heroicons"

Among other benefits, this allows for easier control of icon size using CSS. Example:

{{ $icon := resources.Get "svg/heroicons/20/solid/phone.svg" }}
<span class="w-8 h-auto">{{ $icon.Content | safeHTML }}</span>

I agree we should do that. I originally created this repo as a proof of concept for module usage, but I haven't followed up on this. A pull request would be appreciated and merged.
