Add DeepCurveTool

[falkhofmann]

during some research, i came across this repo with a curvetool variant for deeps.

i have reached out to matt but havent heard back from him. just asked if we could use his code as base.

otherwise we could start our own. but i like the diea to mimic the 2d curvetool. in addition it could be resulting more like sample amount (min/max) etc.

hey guys, i am stuck with this very one. for some reason i cant get the deepPlane to work withing the execute method.

the same logic works in the doDeepEngine method on other nodes.

does someone has an idea on how to proceed?

void DeepCCurveTool::execute()
{
    DeepPlane inPlane;

    ChannelSet needed = _channels;  // _channels is channel mask knob
    needed += Mask_Deep;
    Box box(_roi[0], _roi[1], _roi[2], _roi[3]);  // user defined ROI

    if (!input0()->deepEngine(box, needed, inPlane))
    {  // fails here to initialise the DeepPlane
        std::cout << "cancel upfront" << std::endl;
        std::cout << "box: " << box.x() << " " << box.y() << " " << box.r() << " " << box.t() << " " << std::endl;
        std::cout << "channels  " << _channels << std::endl;
        std::cout << "inPlane box: " << inPlane.box().x() << " " << inPlane.box().y() << " " << inPlane.box().r() << " " << inPlane.box().t() << " " << std::endl;
        std::cout << "inPlane channels: " << inPlane.channels() << std::endl;
        return;
    }

output:
cancel upfront
box: 36 44 794 570
channels rgb
inPlane box: 0 0 1 1
inPlane channels: none
