FP2-1599: Enable Denoise in std camera settings

Without denoise there was a lot of line noise in the pictures.

Enabling denoise surpresses the line noise effectively while maintaining
a good overall IQ.

This change also enables zero shutter leg in order to remove unwanted delay
between taking pictures.
