- Fix README CMake version mismatch: update from >=3.10 to >=3.16
  to match CMakeLists.txt requirement
- Fix Windows MSVC import library conflict: when BUILD_BOTH_LIBRARIES is ON,
  both static and shared libraries would produce cpp_dotenv.lib on Windows.
  Add IMPORT_SUFFIX "_shared.lib" to the shared library's import library
  to avoid this conflict on Windows/MSVC.
