Idea: Switch from makefile to `go generate` instructions

[matheusd]

Instead of relying on a makefile to generate bindings for the serializers that rely on code generation, we should move those instructions into each serializer package, so that it is their responsibility to keep them correct and up to date and also include instructions on the necessary setup needed to perform the codegen.

This would make the project more in line with purely go projects, removing the need to rely on an additional tool (make) to completely rebuild the project.
