[ENHANCEMENT] Add support for more complex starter code

[gregbell26]

Description

Issue

Some classes use more complex starter code configurations. (nested folders and files)

Suggestion

The autograder should be able to support this when building student the student autograder

Acceptance Criteria

• [ ] Complex file structures should be able to be pulled into the autograder.
• [ ] One to one map of starter_code_src to student_work
• [ ] Single file starter code is still supported.

[gregbell26]

This will be needed before the student autograder is deployed for CSCI200 and CSCI210

[gregbell26]

This should be a pretty easy feature to add
