v2.4.0

This minor version increment changes the behavior of the price and confidence fields so that they are only defined if the product currently has a valid price. This change should prevent downstream users from accidentally using these fields when the trading status indicates that they are invalid. It also includes an update to the solana web3 version that fixes a memory leak in an underlying library.
