Migrate `gamer-profile.js` to echo-base

[Jaden51]

Description

This is the first issue to start migrating the backend functionality over to echo-base. This issue takes the current implementation of the gamer-profile route in Express.js and writes the code in Go. The functionality should mostly stay the same but making improvements to the original implementation.

Requirements

• You can get a student via their student_number in the database.
• You can post a new student with the correct information.
• You can delete a student via their student_number in the database
• Write tests
