Summary

This release expands the options modeling capabilities by introducing new core structs (OptionInstrumentPair, Spread, BasicGreeks, BasicOptionData) with serialization support and comprehensive testing. It also streamlines code formatting, improves JSON display handling with pretty_simple_display, and introduces enhanced coverage reporting.

• Standardized formatting across the codebase:
  • Consistent spacing and alignment of method chains.
  • Removed redundant clone() calls in favor of direct assignments.
• Exported OptionInstrumentPair via prelude.rs for easier integration.

Documentation Updates

• Added detailed documentation for:
  • Spread
  • BasicGreeks
  • BasicOptionData
