FT Transformer applied to sequential tabular data

Sequential FT-Transformer

This is an adaptation of the FT-Transformer model architecture for sequential data. The model has been reworked from Antons Ruberts Tensorflow FT-Transformer implementation. In addition to changing the model to support sequential data, the model has undergone numerous changes to enable support for Keras 3. Some design changes have also been made to allow for more flexibility. For example the old implementation required passing numpy arrays through the model to create the bins for the PLE numerical embedding layer. This has been moved out of the model, since it creates a bottlneck when performing distributed training using Horovod for example.

Installation
