switching from recursion to a loop. In theory, determining the column name can go to infinity

One line description of your change (less than 72 characters)

Allows for any number of columns for the CSV wide template.

Problem

The previous update supported columns up to AAA (roughly 700 column), but then provides an undefined in the string that is being constructed afterwards.

Solution

Changed the recursive solution for one with a loop and builds out the string that way. Now the column size can grow to any length, though highly unlikely.

Test Plan

I added some simple test cases that demonstrate the problem and didn't previously exist for the function

Makes sense! I initially wanted to get in a quick fix but it's a good call to get rid of the column limitation going forward
