bug of function set_COOLCONF

[chaoshuzhe]

line 727 of Trinamic_TMC2130.cpp should use TMC_COOLCONF_MASKS not TMC_CHOPCONF_MASKS. Is it a typo?

[hexeguitar]

Apart from that all the COOLCONF altering functions are wrong, ie

uint8_t Trinamic_TMC2130::set_sfilt(uint8_t value)
{
  set_CHOPCONF(TMC_COOLCONF_SFILT, value);

  return _status;
}

which alters the CHOPCONF reg instead of COLLCONF.
