[BUG] print_list macro does not honor capitalization

[aroder]

Describe the bug
There is a macro named print_list that prints a list of columns, useful in dynamic select statements. However, it assumes all column names are all capital letters, which is the default behavior of snowflake

Expected behavior
Columns with mixed case can take samples without error

To Reproduce
Create a table with forced mixed case "exampleColumn"
Configure re_data to take samples from the table
Attempt to run re_data
