update ETL for new EMSL format

[mslarae13]

The EMSL submission portal will be fully rolled out in FY26.
We no longer have macro excel files.
Update the ETL to adhere to the new structure.

Contact @mslarae13 for excel templates.
On export, can we exclude empty columns?

@cristina-stonepedraza any update on this? Is this actively being worked on?

@ssarrafan I've been sick, so I have not been able to work on this issue this week. I talked with Montana and we decided we would move this to next sprint. This issue is also linked with #67, and takes priority over that one, so that will be pushed as well.

Moving out of the sprint. Some decisions to be made.
