[felipejfc]

Is your feature request related to a problem? Please describe

Adding a new functionality for tuya lights.

Describe the solution you'd like

It will be possible to use scenes with breathing and flashing cycles with tuya lights.

Describe alternatives you've considered

There's no alternative.

Additional context

This is what the screen in the app look like:

Did some sniffing of a bulb here with this functionality and saw this data flowing from the tuya gateway to the light bulb when cycling through the different scenes:

night (static) f1 00 00 28 28 00 00 00 00 c8 00

From deduction, here are some assumptions, lets take gorgeous:

f1 07 3f f1 -> command 241 07 -> scene id, see how it increases from one to the other in sequence same as they're presented in the app screen 3f -> this one I THINK is a bitmask indicating how many colors the breath flows will have, 3f = 00111111 in binary, 6 bits set and 6 colors selected.

the rest is an array composed of speed, color and brightness info:

46 46 00 f0 e8 e8 00 00 46 46 -> speed? 00 -> hue, first color is red f0 -> saturation? e8 -> lightness? e8 -> probably brightness the one that you set in the slider on the top, see how it's lower in the (lower brightness) example. 00 00 -> I'm not sure, althoigh given it's being set to values in the first static examples maybe this one controls white led temperature and so on?

other 5 colors only changing Hue and Saturation

46 46 78 f0 e8 e8 00 00 46 46 f0 f0 e8 e8 00 00 46 46 3d f0 e8 e8 00 00 46 46 ae f0 e8 e8 00 00 46 c6 13 f0 e8 e8 00 00

I think supporting the breath and flashing ones would be super nice. There's no good way (that I know of?) of doing these color cycles currently. From reading thorugh different parts of z2m code I think we basically need to create a new command interpreter for this f1 (241) cmd, and construct the arrays for passing the colors info to the light? Though I prefered to post this here before giving a go since there might be a easy/right way of doing it that a newbie in the project wouldn't know :)
