CTHUB - Make Column Casing Consistent

[JulianForeman]

Task Description Create a preparation function for the GER upload (potentially all uploads, ask Katia about this) that keeps the title of each column's capitalization consistent.

Purpose It makes it more readable and also allows for us to better check what is inside a cell in the future for duplicates/naming schemes etc...

Acceptance Criteria

• [ ] The read/returned columns should all be capitalized the same way

Development Checklist

• [ ] Create either a re-usable preparation function for specifically GER or write it into the actual uploader to capitalize column names the same way.

Additional context Please see GER Notes 1.1 located in the GER_Notes file contained in the shared CTHUB folder in Teams.

We can use built in functions to make everything capitals or lowercase or title structure so this shouldn't be much work.
