deeddy df733199b4 price-trends: add sale-frequency data (how often drives discount)

Per-model and weekly computed figures: how often each current 8TB+ drive
goes on sale (best price 5%+ below its own rolling-median baseline) and how
deep. NAS lines discount several times more often than enterprise; similar
depth. Computed values only, compiled from Amazon price history.
