/**
 * Creates a hook for computing PDAs (Program Derived Addresses) with caching
 *
 * @param pdaFn - A function that computes a PDA from some arguments
 * @param queryKeyPrefix - A unique prefix for the react-query cache key
 * @returns A hook that computes and caches the PDA
 *
 * @example
 * ```typescript
 * import { findAssociatedTokenPda } from "@solana-program/token";
 *
 * const useAssociatedTokenPda = createPdaHook(
 *   findAssociatedTokenPda,
 *   "associatedTokenPda"
 * );
 *
 * // In a component:
 * const { data: pda, isLoading } = useAssociatedTokenPda({
 *   mint: mintAddress,
 *   owner: ownerAddress,
 *   tokenProgram: TOKEN_PROGRAM_ADDRESS,
 * });
 * ```
