Refactor: RipOptions parsing could be split into separate concerns #28
Description
Consider splitting RipOptions parsing into separate components:
- RipOptionsParser - handles command-line parsing
- RipOptionsValidator - validates the options
- RipOptions - pure data class
Location: src/RipSharp/RipOptions.cs
Currently the ParseArgs method mixes parsing with validation and default value assignment.
Priority: Low - Nice to have refactoring for improved clarity
