dsROCrate 0.2.2

Bug fixes

• Fixed an issue in safe_output() where Opal audit logs containing no AGGREGATE events could cause the audit pipeline to fail when constructing the calls table.
• safe_output() now handles audit sessions with logs but no AGGREGATE calls gracefully, returning an empty calls table rather than attempting to operate on NULL.
• Fixed an issue where an RO-Crate without an explicit Opal profile attribute could cause safe_output() to fail when filtering audit logs. The default "default" Opal profile is now used when no profile is supplied.
• Improved robustness of provenance extraction for audit sessions with incomplete or limited audit activity.
