Confu - YAML based command-line argument parser generator

WIP.

Intent - create a tool that would generate a Zig specific (support more languages later?) command-line argument parser based on a YAML provided configuration.

• Core Ideas
  • Confu should only be a develompent time dependency
  • Confu should be able to generate a Zig file that can be included in the project
  • Confu generated code should be easy to use
