Dependency updates

[CarstVaartjes]

A PR to update older dependencies to prevent running into issues in the near future.
NB: currently still running into some ZSTD issues when compiling, will ask as an issue

@CarstVaartjes: Any luck fixing the ZSTD issues? Would be great to get this merged in because of deprecations in third-party libraries (e.g., pandas.DataFrame.from_items is now gone). Happy to help test this out, but not sure what the status is.
