Exports a mapping of entries to public paths of chunks

# entrypoint-assets-webpack-plugin

Exports a JSON file that maps entry names to public paths of chunks for an entry grouped by chunk file extensions.
```json
{
    "site": {
        "js": [
            "/public/common.js",
            "/public/site.js"
        ],
        "css": [
            "/public/common.css",
            "/public/site.css"
        ]
    },
    "admin": {
        "js": [
            "/public/common.js",
            "/public/admin.js"
        ],
        "css": [
            "/public/common.css",
            "/public/admin.css"
        ]
    }
}
```

This mapping can then be used to generate import assets in HTML by entry name not the asset names.
