Add product arg to LicenseManager.SetLicense

Update to match C++ API change requiring a product parameter for SetLicense. Bump radarsimcpp submodule pointer, modify radarsimpy/includes/radarsimc.pxd to add the product string argument to both SetLicense overloads, and update src/radarsimpy/license.pyx to pass cpp_product = b"RadarSimPy" in all code paths (single path, multiple paths, and empty/free-tier). This ensures the Cython bindings call the new C++ signature.
