/**
 * test_data.cpp — Standalone console test for the dump1090 data pipeline.
 * Builds with MSVC (no LVGL, no SDL, no Arduino).
 *
 * Compile from Developer PowerShell:
 *   cl /EHsc /std:c++17 /DPC_SIMULATOR /I src test_data.cpp src\aircraft_data.cpp src\coord_convert.cpp /Fe:test_data.exe /link ws2_32.lib
 *
 * Or from regular PowerShell after running vcvars:
 *   & "C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvars64.bat"
 *   cl /EHsc /std:c++17 /DPC_SIMULATOR /I src test_data.cpp src\aircraft_data.cpp src\coord_convert.cpp /Fe:test_data.exe /link ws2_32.lib
 *
 * Then run:
 *   .\test_data.exe
