Stop using boto3?

I haven't verified yet, but I think boto3 only works with instances in the correct security group or for users who have authenticated using the aws cli. This adds one extra step to getting people started, so instead of using boto, we should consider using:

data = requests.get(s3url).content

Looks like it's now possible to read without credentials using:

import s3fs
s3 = s3fs.S3FileSystem(anon=True)
s3.get('twde-datalab/raw/filename.csv', '../data/filename.csv')
