Bug Description

Description:
Build fails with the following error when compiling with CUDA 12.9 and Visual Studio 2022:

error : function "flamegpu::DeviceAgentVector_impl::VariableBufferPair::VariableBufferPair(const flamegpu::DeviceAgentVector_impl::VariableBufferPair &)" (declared implicitly) cannot be referenced -- it is a deleted function
...
instantiation of "std::list<_Ty, _Alloc>::list(const std::list<_Ty, _Alloc> &)" at line 320 of ...DeviceAgentVector_impl.h

Reproduction steps:

auto cell_api = api->agent("Cell");
auto pop_data = cell_api.getPopulationData();
for (size_t i = 0; i < pop_data.size(); ++i) {
const auto& agent = pop_data[i];
}

Environment:

Windows
CUDA 12.9
Visual Studio 2022
FLAMEGPU2 (latest release)
Expected behavior:
Build should succeed when using getPopulationData and accessing agents by reference.
