Description
The [changelog](https://google-grain.readthedocs.io/en/latest/changelog.html) states that `IterDataset.mp_prefetch` would use multi threading when `free-threaded Python is detected`, though there are currently no wheels available on pypi that support free threading.
If you try to create an uv project with python 3.13t or 3.14t, then you would get an error
```
error: Distribution `grain==0.2.16 @ registry+https://pypi.org/simple` can't be installed because it doesn't have a source distribution or wheel for the current platform
```
Is there a workaround? Or are there any plans to build grain against the free threading versions of python?
