Make quality scaler downscale faster.

Include dropped frames by the encoder in the frame drop percentage.

To react faster at low framerates:
- Use ExpFilter instead of MovingAverage to filter QP values.
- Reduce sampling interval while waiting for minimum number of needed frames (when not in fast rampup mode).

A separate slower ExpFilter is used for upscaling.
