Decimate modifire: support for retopology for games

With the advent of UE5 and Nanite technology in large studios, the pipeline for creating 3D environment assests has changed. Now for retopology it is enough to use Decimate modifier, which reduces number of pollygons from 1000 to 20000 triangles per asset (sometimes more, sometimes less). BUT current algorithm of Decimate modifier has some disadvantages, because of which it takes a long time to clean model. The current algorithm tries its best to preserve detail of the object, while leaving long triangles or excessive detail on the planes. It would be useful to add an analogue of the Decimate modifier, but with a modified algorithm, without these drawbacks.
