Add Safari Browser History (#49)

Adds a Safari Browser History definition that parses the History.db
database on macOS. Joins history_items and history_visits tables to get
a per-visit browsing timeline.

Note that Safari's data directory (~/Library/Safari/) is protected by
macOS TCC. The Velociraptor agent must have Full Disk Access for this to
return results.
