Configurable channels for multi channel types (like rgb or color_temp)

[turboPasqual]

Right now (v0.1.17) there is always a distance of 1 between each channel for a multi channel type.

Let's take the example from the readme:

• channel: 3 name: my_rgb_lamp type: rgb transition: 1 channel_size: 16bit output_correction: quadratic channel_setup: rbgw # Auto-calculated white channel

Although the channel_size is 16bit, channels 3, 4 and 5 will be used for red, green and blue. It would be correct to use 3, 5 and 7. (At least with my DMX controllers. But I guess this is always like this.) So I can just use single channels or need to use 8bit size. In my oppinion it would be even better to let me configure those channels. I have some rare cases where the channels are not in a row (e.g. red=1, blue = 5, green = 11).

I have just realised that this might be an explanation for issue #46 Transition is flickering.

That's very strange. Using your exact configuration, it outputs in 16-bit chunks.

In my oppinion it would be even better to let me configure those channels

Try this:

        - channel: 1
          name: my_rgb_lamp
          type: rgb
          transition: 1
          channel_size: 16bit
          output_correction: linear
          channel_setup:
            - r
            - 0
            - g
            - 0
            - b

On further testing I noticed that this works fine although it gets displayd wrong. I have an rgb light using the 16 bit channels 409/411/413 and it works as expected. But in the guy it looks like this:
