v2.0.0 - Rewrite in modern C++17 to get better performance

v2.0.0

Highlights

• Complete rewrite in modern C++17 — still a single header, same public API
• Removed the legacy C parser (malloc/fgets/char buffers) and C API (ini_parse*, ini_handler, INI_* macros)
• Zero-copy parsing with std::string_view; numeric conversion via std::from_chars (auto-fallback on older compilers)

Performance (GCC 13, -O2)

• Parse: 2.2× faster
• Get<int> / Get<std::string>: ~100× faster (old version copied the whole section map on every call)
• GetVector<double>: ~20× faster
• Peak memory: +8%

Changes

• No more 2000-char line limit or 49-char section name truncation
• Breaking: C API removed; duplicate keys with empty first value now throw
• Fixed: uninitialized _error on default construction; UpdateEntry no longer creates empty entries on failure
• Tests: 13 → 27 (BOM, CRLF, comment rules, error messages, numeric edge cases, FILE* ctor, writer overwrite)
• Verified on GCC 7.5–13, Clang 17, MSVC 2019+
• Docs: API reference added to README; doxygen docs regenerated warning-free; CI bumped to checkout@v4
