Better icons mgmt

[Spomky]

Description

At the moment, the icons must exist as an asset to be linked to the Manifest file.
Without changing the configuration, it could be great to generate them on-the-fly when compiled

Example

pwa:
    icons:
        - src: "images/pwa/favicon.svg"
          sizes: [48]
          format: 'ico'
        - src: "images/pwa/favicon.svg"
          sizes: [96, 128, 256, 512, 1024]
          format: 'png'
        - src: "images/pwa/favicon.svg"
          sizes: [0]
        - src: "images/pwa/favicon.svg"
          purpose: 'maskable'
          sizes: [0]

Note that only 1 asset really exist

Manifest file in dev/prod

{
    "icons": [
        {
            "src": "/assets/pwa/favicon-xxxhashxxx.ico",
            "format": "image/ico"
            "sizes": "48x48"
        },
        {
            "src": "/assets/pwa/favicon-xxxhashxxx.png",
            "format": "image/png",
            "sizes": "96x96 128x128 256x256 512x512 1024x1024"
        },
        {
            "src": "/assets/pwa/favicon-xxxhashxxx.svg",
            "format": "image/svg",
            "sizes": "any"
        },
        {
            "src": "/assets/pwa/favicon-xxxhashxxx.svg",
            "format": "image/svg",
            "purpose": "maskable",
            "sizes": "any"
        }
    ]
}

What do you think of having a default favicon in the bundle, with instructions on how to customize? It seems like the first error I always get is favicon failing.

Closing as not mature for now.
