Function calls in Pyxel fail when using Maturin 1.7.1 or later

[kitao]

Bug Description

Hi.
I tried compiling Pyxel with Maturin 1.7.1+.

I changed an option in Pyxel's makefile from --skip-auditwheel to --auditwheel skip and then the compilation finished.
But when run an application, the following error occurs:

    pyxel.init(300, 300, title="hoge")
    ^^^^^^^^^^
AttributeError: module 'pyxel' has no attribute 'init'

Maturin is called from Pyxel's makefile. https://github.com/kitao/pyxel/blob/main/Makefile#L102

The directory structure of Pyxel may no longer work correctly with Maturin 1.7.1 or later.

Your maturin version (maturin --version)

Your Python version (python -V)

Python 3.12.3

Your pip version (pip -V)

pip 24.2

What bindings you're using

Does cargo build work?

• Yes, it works

If on windows, have you checked that you aren't accidentally using unix path (those with the forward slash /)?

• Yes

Steps to Reproduce

Just build Pyxel and use it.

• Build with make
• pyxel edit (which calls some Pyxel functions and invoke the error)
