Pyxel doesn't work with the latest Maturin (> 1.7.0)
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'
```

@messense
Is there any other setting I should change?
