Early progress on an app whose sole purpose is to "get me this file from S3 as fast as possible".

Usage:

$ ./s3me
Usage of ./s3me:
  -c=1: Number of connections
  -o="./output": Output path
  -s=0: Number of segments
  -u="": -u https://bucket.s3.amazonaws.com/key

$ ./s3me -u https://bucket-name.s3.amazonaws.com/filename.mp4 -c 4 -s 16 -o ~/Desktop/output.mp4
