• Fixed handling of the aggregated data to use correct minute in time. (Previous impl. results in several "Ping Snapshots'" per minute, compared to one per minute as intended. That resulted in increased iteration and memory usage for the same data output.)
• Also moved some of the computation and caching of deviation and fluctuation into the "Snapshots'" to reduce over all computation.
  
• Improved inventory handling to update the specific content changes in cache and inventory without entirely regenerating page.
• Also supports 1.21 (Natively, nothing broke it.)

(Memory usage is approx. 28MB per 350 players or 80KB per player over a 24hr span)
More is planned, such as implementing charts and graphs. Stay tuned!
