The implementation of the RNN_DynEdge model

Created by: Aske-Rosted

An implementation of an model that first puts the DOM data through an RNN network before feeding it to the DynEdge network, along with some functions working on DOM level data in order to facilitate the RNN.

This is a way of tackling the issue which is also addressed in #474 (closed).

Due to limited hardware on my end I have not had the ability to properly performance check this new model.
