 * @description BIP32 Path Handling for Aptos Wallets
 *
 * This file provides utility functions to handle BIP32 paths,
 * which are commonly used in hierarchical deterministic (HD) wallets.
 * It includes functions to convert BIP32 paths to and from different formats,
 * extract components from extended public keys (xpubs), and manipulate path elements.
