fix(build): Updating the output directory of the Makefile

[Jacobbrewer1]

Background

In order to keep things in the repo clean and streamlined, I have moved the build of the Makefile to output the binary into a bin/ subdirectory.

This prevents binaries being lost in the root of the repo and causing problems.
