Correct an invalid jpeg quality parameter.

With our new libjpeg_turbo library, a quality of 150 doesn't seem to be valid, so I'm changing this to 95. I chose 95 over 100 because the libjpeg_turbo project uses a quality of 95 for all testing and benchmarking shown in their documentation, and notes that a quality of 95 "has been determined to be perceptually lossless under most viewing conditions".
