S3 intra-bucket deduplicator.

• Ensure you have your AWS credentials set up.
• Run node get-bucket-objects.js --bucket=mybucketname. This will churn for a while - approximately 1.5 seconds per 1000 objects in the bucket. When it's done, mybucketname.bucket.json will be written to cwd.
• Run node analyze-json.js --file=mybucketname.bucket.json. It will print a list of duplicate groups, largest first.
  • You can add --include REGEXP [REGEXP...] and --exclude REGEXP [REGEXP...] to filter objects by name.
  • You can add --interactive to have the program prompt you for the files to delete within each group.

❗ As it is, s3-dupes does not hash your objects! This means false positives are entirely possible.
