/size doesn't work for images built for multiple platforms

[frysztak]

I have an image (frysztak/orpington-news) built for both amd64 and arm64. badge returns size 0:

I think that happens because GHCR API returns the following when querying for manifest:

$ curl -H "Authorization: Bearer $(echo "v1:frysztak/orpington-news:0" | base64)" "https://ghcr.io/v2/frysztak/orpington-news/manifests/latest"
{
   "mediaType": "application/vnd.docker.distribution.manifest.list.v2+json",
   "schemaVersion": 2,
   "manifests": [
      {
         "mediaType": "application/vnd.docker.distribution.manifest.v2+json",
         "digest": "sha256:0d73ad2cd04d706bd51cfb5e5025050f2722d87d8b361db1d3503420baf52313",
         "size": 5535,
         "platform": {
            "architecture": "amd64",
            "os": "linux"
         }
      },
      {
         "mediaType": "application/vnd.docker.distribution.manifest.v2+json",
         "digest": "sha256:1c4b3de94974de6919bfc8ea83ef295f5ac5065c9f8b7d83ae5cd1fe8644ffbf",
         "size": 5535,
         "platform": {
            "architecture": "arm64",
            "os": "linux"
         }
      }
   ]
}

and generate.py expects it to be a "mediaType": "application/vnd.docker.distribution.manifest.v2+json"

wow, that was quick. thanks! however, it now seems to return manifest size rather than sum of layer sizes. to fetch those, you need to do another call API with image digest as tag. for example, for amd64 image: https://ghcr.io/v2/frysztak/orpington-news/manifests/sha256:0d73ad2cd04d706bd51cfb5e5025050f2722d87d8b361db1d3503420baf52313
