Create Fade Mask Advanced

Create a batch of masks interpolated between given frames and values. Uses same syntax as Fizz' BatchValueSchedule. First value is the frame index (not that this starts from 0, not 1) and the second value inside the brackets is the float value of the mask in range 0.0 - 1.0 For example the default values: 0:(0.0) 7:(1.0) 15:(0.0) Would create a mask batch fo 16 frames, starting from black, interpolating with the chosen curve to fully white at the 8th frame, and interpolating from that to fully black at the 16th frame.
