Enhancement: output summary numbers with commas

[YamatoSecurity]

サマリでイベント数が多いと、読みづらいので、コンマを入れたいです。
例：

Total events: 5232442
Data reduction: 4141340 events (79.15%)

Total detections: 2273592
Total critical detections: 66
Total high detections: 431242
Total medium detections: 184054
Total low detections: 128958
Total informational detections: 1529272

を以下にします:
