[Refactor]: Implement better consistent C++ style across project

[thomaslaurenson]

• Currently, this project grew and has some heavy code style inconsistencies
• To help future proof and make the project easier to maintain it need a style refactor
• Moving to be closer to Google C++ style (personal preference)
  • but no k prefix constants/enums, instead use uppercase snake
  • also improve clang format config for this
• DOD: Clang format preferences written and passing

[thomaslaurenson]

• Closed in Refactor/clang style #175
• Summary is switch to Google CPP spec with some variations
