Sendowl Consolidation Script

As self-published authors, Audrey and I use the awesome sendowl service to distribute our digital files. We had multiple storefronts accounts for different countries but now we only need one. This is what I wrote to handle the migration of orders from multiple accounts into just one account.

"""
This converts a Sendowl orders CSV export into a CSV
following Sendowl's import template. Useful for
consolidating Sendowl accounts.
