improper csv encoding in sql repo

Hey all,

I am running through the second book on Mac OS Catalina Version 10.15.3

When going through the sql section I had some issue with the employees.csv.

It turns out that the newline character encoding stored in the csv was not compatible with `cat` in mac osx

and the file encoding was set to `regular file`

I have an update ready to push if you all need.
