Modify GenerateSectionData in the following ways:

1. it should take a second argument which is a list of Users
1. replace the section where Instructors are generated according to config.NumberOfInstructors with a section that makes a list of users with Status "Instructor" from the Users argument

Remove NumberOfInstructors from the Config type and correct all instances of it in the code

Write a function GenerateInstructorAssignmentData that takes a list of Users and a list of Sections and returns an []InstructorsSections.  This should pair instructors with sections, trying its best to distribute Sections evenly between instructors

Write a function SaveInstructorsSections that simply writes this list to a file called "instructors_sections.csv".
