cache expiration after download

[sescobb27]

hi, I would like to have a custom hook to get notified when a download is finished or have access to the caching layer from the downloader, something like the following example, then we can get the new content as fast as we can

const downloader = new Downloader({
  download(){
    downloadPromise.then(() => this.cache.expire(`${key}:${path}`))
  }
})

// OR

let server = new FastBootAppServer({
  ...,
  afterDownload: function () {
    return this.cache.expire(`${key}:${path}`)
  }
})

I think this expiration feature is not present yet, any thoughts? let me know if that sounds good to you and if I can help implementing this. thanks
