This commit introduces a new test file for the NRLMSISE-00 model, implementing the test_gtd7 function. The test evaluates the model's output for various atmospheric conditions and prints the results for verification. The input parameters include day of year, time, altitude, geographic latitude and longitude, and solar activity indices. The output includes temperature and density profiles for different atmospheric constituents.

Introduced internal static Data class containing all published NRLMSISE-00 empirical atmosphere model coefficients as immutable static arrays. Includes temperature, density, and auxiliary parameter tables with detailed documentation. No logic added; this file serves as a reference data container for model computations and validation.

Pull request overview
This PR introduces the NRLMSISE-00 atmospheric model, a comprehensive empirical model for Earth's atmosphere from ground to thermospheric heights. The changes include a significant architectural refactoring of the atmospheric modeling system.
Key changes:
- New NRLMSISE-00 atmospheric model implementation with full support for time-varying, position-dependent atmospheric conditions
- Refactored atmospheric model architecture using interface-based design (
IAtmosphericModel,IAtmosphericContext) - Backward-compatible migration path with deprecated legacy classes
- Comprehensive test coverage including unit tests and integration tests

The XML documentation is incomplete. The param tags for 'year', 'doy', and 'sec' are present but lack descriptions. Consider adding descriptions to explain the valid ranges and meanings of these parameters (e.g., "year - Calendar year (0 defaults to 2000)", "doy - Day of year (1-366)", "sec - Seconds within the day (0-86400)").
