Incompatible license from dependencies

[masadcv]

The maxflow implementation is based on v3.0 of Yuri Boykov's code (see https://pub.ist.ac.at/~vnk/software.html)) The dependency is under: https://github.com/HiLab-git/SimpleCRF/tree/master/dependency/maxflow-v3.0

SimpleCRF is released under a permissive license which is incompatible with GPL license for maxflow code.

There maybe other implementations of the Boykov-Kolmogorov maxflow algorithm that can be used here, e.g. in OpenCV and Boost. One such example is under: https://github.com/luiscarlosgph/grabcut/tree/main/inc/grabcut
