* CCID: Improve request and response data handling - Add iso7816_set_response function: serves a helpers to set SW1 and SW2 values - improved iso7816_read_response_apdu by correctly parsing Lc and Le values - add client script to make testing easier * lint and rename * Format * Review changes: pragma once, typedef * Move command/response data and datalen into respective structures * Remove conditional for Lc=0 * Fix comment: Le * Make PVS happy and fix spelling Co-authored-by: あく <alleteam@gmail.com>
