Fix flex filter excluding valid low-price intervals in best price periods (#68)

Browse source 
Fixed bug in best price flex filter that incorrectly excluded prices
when checking for periods. The filter was requiring price >= daily_min,
which is unnecessary and could theoretically exclude valid low prices.

Changed from:
  in_flex = price >= criteria.ref_price and price <= flex_threshold

To:
  in_flex = price <= flex_threshold

This ensures all low prices up to the threshold are included in best
price period consideration, matching the expected behavior described
in the period calculation documentation.

The fix addresses the user's observation that qualifying intervals
appearing after the daily minimum in chronological order should be
included if they meet the flex criteria.
