If I can cimport the cython .pxd files from pyarrow directly

Recent days, I have develop a new dataset filesystem used in my company scope. But in the python environment my colleague use the dataset api and inject the filesystem which I have wrote. Hence I have to make a new python wrapper for the new filesystem. But I am a newbie of cython I don't know if I can cimport the .pxd files from the pyarrow I have installed (built with my filesystem)

example is that

```python
# my/path/to/filesystem.pyx

# I don't know if this statement is valid ?
from pyarrow.includes.common cimport *
```

Start by checking the installed pyarrow.includes.common .pxd path and the example my/path/to/filesystem.pyx. Verify whether a downstream Cython module can cimport those files from an installed PyArrow build, then document the supported import and build requirements, or clarify that this use is unsupported.
