变更概述
本次 PR 为 pyqpanda-algorithm 项目新增完整的 VQE（Variational Quantum Eigensolver，变分量子本征求解器）算法模块。
新增文件
pyqpanda_alg/VQE/__init__.py— VQE 子包初始化，导出 VQE 类和 hardware_efficient_circuit 函数pyqpanda_alg/VQE/vqe.py— VQE 核心算法类，支持 PauliOperator/Hamiltonian 输入、自定义 ansatz、scipy 优化器pyqpanda_alg/VQE/ansatz.py— 硬件高效参数化量子电路（ansatz），使用 RY/RZ 旋转门和 CNOT 纠缠门example/VQE/example_vqe.py— VQE 使用示例test/VQE/Test_VQE.py— 单元测试修改文件
pyqpanda_alg/__init__.py— 启用 VQE 模块的包级导入功能说明
