pocketpy has provided a low-level API for creating bindings. It is fast, lightweight and easy to debug. However, it still requires a lot of boilerplate code to create bindings for complex C++ classes. The community has long expected a high-level API for creating bindings.

pybind11 is the most popular C++ library for creating Python bindings for CPython. A bunch of Python libraries are using it. pybind11 adopts a template metaprogramming approach to automatically generate bindings for C++ classes.

Our goal is to introduce a pybind11 compatible solution to pocketpy as an alternative way to create bindings for functions and classes. You can use C++17 features to implement it, instead of C++11 used in pybind11.

### Add `numpy` module

- Difficulty Level: 4/5 (Intermediate)

Though pocketpy is designed for game scripting, some people are using it for scientific computing. It would be nice to have a `numpy` module in pocketpy.

`numpy` is a huge project. Our goal is to implement a most commonly used subset of `numpy` in pocketpy. You can mix C++ and Python code to simplify the overall workloads.
