pace temperature framework: controller fixes
various issues with the controller implementation:
self.__ramp_rate = self._pace._ramprate(self.channel)
stores a string instead of a float so rate = int(kwargs.get("rate", self.__ramp_rate))
is failing.
self._pace.ramp(self.channel, sp, rate)
=> wrong args order
toutput.rampval(rate)
=> rampval() does not exist !
