Multiple uLipSync instances created causing calibration button to not work

[jamesw966]

I've been trying to calibrate but the button doesn't work for me - the visualisation for the phoneme stays exactly the same colours when I push the button. However, I know the sound is coming through because I can see my avatar's lips moving in response to sound from a file or the mic.

I discovered that many instances of the uLipSync class were being created and the calibration requests were being handled in a different instance to where the button click was handled. To diagnose this I created a class constructor and made a random ID there, which I printed out immediately but also in the RequestCalibration() and UpdateCalibration() methods.

As a workaround, I've changed _requestedCalibrationVowels to be static and now it works fine. If I find out why multiple uLipSync instances are being made then I'll follow up.

I'm on Unity 6 using uLipSync 3.1.4.
