hubData 2.2.1

• Fixed bug in collect_hub() that caused returned tibbles to contain arrow-ALTREP-backed columns rather than plain materialised R vectors (#141). The ALTREP views could not be safely save()d, serialize()d, or sent to parallel workers in R sessions without arrow installed, silently corrupting columns (most came back length-0). collect_hub() now sets arrow.use_altrep = FALSE for the duration of the call, restoring the long-standing dplyr::collect() contract of materialising into plain in-memory R vectors. Users who want lazy / ALTREP-friendly access can continue to use connect_hub() and work with the arrow dataset directly.
