Added a remesh_mesh function similar to triangulate_mesh used by the triangulate node. It was added so the function and structs don't need to be rewritten and more code can be shared.

We can talk more about this in the chat if you'd like, but I wouldn't consider the triangulate node as an example of the proper way to do this, it was mainly a prototype in the very beginning of the process.
The code should be added in the node, and generalized where necessary / helpful. Some of those decisions might not be trivial, but they're worth discussing.
