 The pyth program accumulates prices with respect to whatever the current slot is inside the solana node. This is called the "valid_slot" above. As soon as the slot ticks forward by one, the pyth program computes the aggregate price and publishes it with respect to the new "publish_slot" and starts repeating the process with a new "valid_slot".
 
 The aggregate "status" of a price is subject to whether there are any valid contributors (i.e. "unknown" status) or whether any contributors are in a "halted" or "auction" state.
