/**
 * Validates a Brazilian CPF (Cadastro de Pessoas Físicas) number.
 *
 * This function performs a comprehensive validation of a CPF number, including:
 * - Cleaning the input by removing non-digit characters
 * - Checking for the correct length
 * - Verifying that it's not a known invalid CPF (e.g., all digits the same)
 * - Validating both check digits according to the CPF algorithm
 *
 * @param {string} data - The CPF string to validate can include formatting characters
 *
 * @returns {boolean} Returns true if the CPF is valid, false otherwise.
 *
 * @example
 * // returns true for a valid CPF
 * validationCPFIdPerson("123.456.789-09")
 *
 * @example
 * // returns false for an invalid CPF
 * validationCPFIdPerson("111.111.111-11")
