Json Benchmark

Tujuan dari benchmark ini adalah untuk mencari alternative dari package encoding/json. Benchmark ini hanya akan menggunakan 2 usecase yaitu marshal dari struct ke json dan unmarshal dari json ke struct. Library yang tidak mengcover salah satu dari use case itu tidak akan di benchmark. Hasil bisa berbeda beda tergantung dari panjang JSON.
