Only user permission of saved cache files, not group
Note that you can get the cache files of a dataset with the `cache_files` attributes.
Then you can `chmod` those files and all the other cache files in the same directory.

Moreover we can probably keep the same permissions after each transform. This way you just need to set the permissions once after doing `load_dataset` for example, and then all the new transformed cached files will have the same permissions.
What do you think ?
Hello,

It seems when a cached file is saved from calling `dataset.map` for preprocessing, it gets the user permissions and none of the user's group permissions. As we share data files across members of our team, this is causing a bit of an issue as we have to continually reset the permission of the files. Do you know any ways around this or a way to correctly set the permissions?
