preprocess groupphoto images

[clif-os]

• uses s3.getObject instead of ajax to fetch image buffers
• preprocesses the gif's middle frame and uploads it to s3 as a JPEG under /public/photos
• processing now takes about 20-35s for 1,800 images, instead of 1-2 minutes
• use websockets to communicate group photo success/failure (since heroku times out after 30s)

[clif-os]

@julianduque would you like me to write an endpoint that uses your /deleteObj fn() to remove both the gif and the jpeg by their filename?

[crcastle]

Hey @clif-os - These changes are causing an error for me. I'm getting an error when I click "Share with conference" after recording a GIF.

Hey @crcastle I launched this branch here and am not seeing that issue:
https://gif-booth-pr-34.herokuapp.com/new-gif

Is the bucket you're using a bucket that already exists? (This change cannot be placed onto an existing gif booth bucket as it diverges from the file/folder structure).
