Allow independent reference pitch for the magnet and microphone tuners

All the guitars I play are tuned to A440, and the magnetic/clip on tuner works great. When checking the tuning of other instruments using the microphone tuner I'll often be using a different reference pitch based on that instrument, such as A443. Right now when you set the reference pitch for one tuner, it carries over to the other as well. So if I just tuned a woodwind, and then stick the tuner in my guitar, if I don't remember to chage the reference pitch back to A440, then I'll be out of tune. Allowing both tuners to "remember" their own reference would solve this for me.

Hi Robert, I could see how that would be helpful, I've passed on your suggestion to our engineer who worked on this feature and see what he thinks

I think we finished coding this and it will be in the coming firmware update
