Requesting method to change viewpoint using LuminanceProducer

[inochi108]

Regarding the LuminanceProducer, currently there are no way to change the viewpoint (confirmed by David Bignell) unless VideoProducer is also enabled in the xml, but if both LuminanceProducer and VideoProducer are enable it it will also return extra rgb values from VideoProducer along with the greyscale values from LuminanceProducer. I want just the grayscale values.

Below are comments from david:

@inochi108 Hmmm, you are right.
The design of this is all wrong, really.
The XML lets you specify different sizes for each video producer, but Malmo only supports sending everything at the same size.
Similarly only one viewpoint is supported, so allowing each video producer to specify it is very misleading.

Ideally this would all be tidied up, but I don't want to break existing code.
@inochi108 would you add an issue to github to request a way to change the viewpoint with the LuminanceProducer?
