[v1] Verbose logging?

[fflaten]

Consider adding duration astro-icon logs and maybe similar loaded-event for local icons.
Just wasted some time attempting to optimize icon collections because it looked like astro-icon used multiple seconds. In reality it only added 0.5sec.

With astro-icon and components

Without

I'm not sure if there's much to be done from the integration's side here. Maybe we can update the message itself, but we're only logging once after loading all the icons. The rest is just Astro building the project.

Maybe we should log ✓ Loaded icons in 500ms.?

Not critical but I'd personally prefer it.
