 * Derive an Address Lookup Table (ALT) address
 *
 * ALT addresses are deterministically derived from an authority and a recent slot.
 * The slot is typically obtained from getSlot() RPC call.
 *
 * @param authority - The authority that will own the lookup table
 * @param recentSlot - A recent slot number (from getSlot RPC)
 * @param altProgramAddress - Optional ALT program address (defaults to mainnet)
 * @returns The derived lookup table address
 *
 * @example
 * ```typescript
 * import { deriveLookupTable } from './lookupTable';
 *
 * // Get recent slot from RPC
 * const slot = await rpc.getSlot().send();
 *
 * // Derive the lookup table address
 * const lookupTable = await deriveLookupTable(authorityAddress, slot);
 * ```
