Pull request overview
This PR represents a major v2.0.0 release of the Geopack library, implementing comprehensive architectural improvements focused on thread-safety, immutability, performance, and API design.
Changes:
- Replaces mutable shared state (Common1/Common2) with immutable ComputationContext pattern for thread-safety
- Introduces strongly-typed generic vector quantities (CartesianVector, SphericalVector) for better type safety
- Converts data models from reference types to readonly record structs for improved performance
- Adds dependency injection support with ServiceCollectionExtensions
- Implements comprehensive performance optimizations including SIMD vectorization, Math.SinCos, and Math.FusedMultiplyAdd
- Extracts magic numbers to well-documented constants in GeopackConstants
