Added export to CSV format and --endpoint optional

[alaouiali]

Added bin/dynamo-export.js, this will read the JSON files the dynamo-archive.js outputs and transforms it into a CSV file (much easier to work with)
Also, I added an option to specify the local dynamodb endpoint (instead of the process.env)
