title: Custom Json Logger for buildpack golang sdk
body: <p>I have a special use case and have been trying to figure out how to implement this i want to use build pack to build project directly from my golang source code and same time extract the logs out in json formats</p>
  <p>But that seems abortive for me i'm here hoping to get help on how to implement my own stdin output logger for buildpack</p>
  <p>Thanks</p>
