arrow的使用

pandas2.0引入了pyarrow作为可选后端，比numpy的性能提高很多，所以为了改造backtrader,用cython和c++重写整个框架，准备用arrow作为底层的数据结构(backtrader现在的底层数据结构是基于python array构建的)

安装arrow推荐使用vcpkg

git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh
./vcpkg integrate install
./vcpkg install arrow

CMakeLists.txt
