Support for more recent versions of fsspec dependency

[jeffkeller-einc]

Hey! Wondering if there's any appetite for loosening the fsspec>=2022.2,<2025.9 constraint in pyproject.toml.

I know the cap was added in #339, but today fsspec ends up underneath a bunch of other libraries we use, and a few of its transitive reverse dependencies have CVE fixes in versions that need fsspec >= 2025.9. I temporarily have a pins < 1.9.1 constraint as a workaround for now.

Is the cap is still needed? Is it safe to bump (or drop) at this point?

Thanks for all the work on pins!

@jeffkeller-einc Thanks for the report and the additional context around the CVE fixes. We're investigating whether the fsspec upper bound is still necessary and what would be involved in relaxing or removing it.
