Support processing video & audio

[MrOrz]

Implements video & audio processing

• Implementation processMedia() is as proposed in https://g0v.hackmd.io/IqCOZMZLRe-JPMSJIV3yRQ#Audio-amp-Video
• Add unit test
• Log proxied file size to see how much over-sized files are there
  • Video on LINE can be huge (>50MB), which takes more than 1 minute to download, so that Cloudflare will prematurely cut off the response of rumors-api
  • We first record the possible size of these videos and see how we should adapt (maybe process video in job queues in rumors-api)
• Display video / audio in text (thumbnail not implemented yet) in Viewed Articles & Article Detail LIFF

Revamp: Fix Error: node_redis: The SET command contains a invalid argument type of "undefined".

• Currently identical image / media article fast-forward mechanism will trigger the following error:
• This is because we return choosingArticle() in processImage() & processMedia(), but the return signature is not compatible.
• This commit reorganizes the return value of choosingArticle() in processImage() and processMedia() so that it works
