 * Derives the token account address given the wallet address and mint address.

 * Address is 20 byte, 160 bits. Let's say if we want to support 50 billion
 * accounts on 1money. That's about 36 bits. There are 124 bits remaining. In
 * other words, the collision probability is 1/2^124, which is very very low.
 * So, we will be fine to just use the hash of the wallet address and mint
 * address to derive the token account address.
 *
 * @param walletAddress - The wallet address (20 bytes)
 * @param mintAddress - The mint address (20 bytes)
 * @returns The derived token account address
