totp : rework and add SHA256/512 (#151)
* totp : rework and add SHA256/512 * totp : comment code * totp : fix SHA224/SHA384 and examples * totp : fix bug in totp_face_lfs * totp : init_totp_record to SHA1 * totp : move TOTP-MCU to TOTP, update README and example * totp : SHAX, use size_t n instead of harcoded 8 * clarify what to put in TOTP face Co-authored-by: Emilien <Emilien> Co-authored-by: joeycastillo <joeycastillo@utexas.edu>
