Figure out different asset domains based on which CDN provider

asset.ts

const hosts = {
  cloudFlare: "https://flosports-video.s3.amazon.com",
  stackPath: "https://cdn.stackpath.flosports.tv",
};

function isStackPath(request: Request): boolean {
  const url = new URL(request.url);
  return !!url.hostname.match(/stackpath/);
}

export function getAssetHost(request: FloRequest) {
  return hosts[isStackPath ? 'stackPath' : 'cloudFlare'];
}
