add option to disable waves

[Sedrowow]

The wave feature is dropping my and other peoples frames.
as suggestion maybe add an option to disable waves and/or make them less performance heavy?

Same here. The water is super laggy. I have only 3fps when creative fly over ocean.

The wave renderer is taking up 21% of my render thread so this really needs to be an option
