 * @name            encodeUserIdentifier
 * @description     Placeholder function for encoding user identifiers (this will be used in the one-way hashing operation to obfuscate client-side userIdentifiers/customerDefinedIdentifiers 
 * @                before they are sent to the server, to protect user privacy). Currently, this function is defined as (and being USED as) a no-op - it simply hands back the input as-is, 
 * @                but this will be replaced with the actual encoding function once the hashing mechanism has been finalized and implemented.
 * @param           {string}        userIdentifier          The user identifier to be encoded (e.g., email, username, etc.)
 * @returns         {string}                                The encoded user identifier
 * @throws          {TypeError}                             If the input is not a string or is missing
 * @memberof        UMFAClientBase, FIDO2ClientBase
 * @example         const encodedId = encodeUserIdentifier("some@email.com");
