New features integration test

[atruskie]

@cofiem is blasting away some issues.

In particular, there are some pretty big changes to the way we process audio which are making me nervous.

We need to test:

• WAac decoding (harvested wac files keep wav file as original, closes #35 #49)
• FLAC encoding of original data ([WIP] add ability to convert original audio to flac for storage #50)

Test protocol:

• record 2 by 6 hour long files on an SM3 in WAac format
• create a project on staging with 3 sites named
  • WAac
  • WAV
  • FLAC
• Upload the audio to each site
  • WAac site: just upload the original files (files 0..1)
  • WAV site: run wac2wav on HPC first,, then upload (files 0..3, where 2..3 are same files with 1s trimmed, expect 0..1 to be rejected)
  • FLAC site: use the WAV file from WAV site, this time turn on harvester's encode as FLAC option (files 0..5, where 2..5 are same files with 1s trimmed, expect 0..3 to be rejected)

Things to check:

• website rejects duplicates
  • if we try and upload wav to wav site, after uploading to wac site, files should be rejected
  • if we try and upload wav, which is encoded to FLAC, then the files should be rejected
• media generation works and is fast
  • at start of files
  • at end of files
• all files have the correct metadata
• other things?...
