 Exports historical expiration data from the genesis ledger to the provided end-ledger to an output file. The command reads from the bucket list, which includes the full history of the Stellar ledger. As a result, it should be used in an initial data dump. In order to get expiration information within a specified ledger range, see the export_ledger_entry_changes command.
