Challenge 10: Price Time Priority

Orderbooks usually use price-time priority.

Task

Implement sort_by_priority.

Rules

For bids:

  1. higher price first
  2. earlier timestamp first at the same price

For asks:

  1. lower price first
  2. earlier timestamp first at the same price

This is what makes matching deterministic and fair among same-price orders.
