Besides, changes for credits are needed as this PR uses code from PythonCall.

Small example for test:

import TyPython.CPython
import TyPython.CPython: py_coerce, py_cast, Py
CPython.init()
CPython.init_jlwrap()
struct Point
    x
    y
end
a = Point(1,2)
pya = py_cast(Py, a)
# Py(<jl p(1, 2)>)
pya.x
# Py(1)
pya.x = py_cast(Py, nothing)
# Py(None)

function f(x, y, z; a, b, c)
    @show x, y, z
    @show a, b, c
    return 1
end
pyf = py_cast(Py, f)
pyf([py_cast(Py,i) for i in (1, true, nothing)]...; a=py_cast(Py, "a"), b=py_cast(Py,0.0), c=py_cast(Py, rand(2,3)))
# (x, y, z) = (1, true, nothing)
# (a, b, c) = ("a", 0.0, [0.8484332315447124 0.9791275442163967 0.7543573420348929; 0.6921301635292861 0.2314489986814141 0.5471932798687941])
# Py(1)

Todo:

• [x] operators +, -, * /, etc.
• [x] __dir__
• [x] handle error
• [ ] doc
• [ ] api in jnumpy

Would finish this work in another repo.
