Support for additional hyperparameters

[qychen2001]

Very good work! But when I wanted to use hyperparameter search for thesis result reproduction, I realized that the implementation of this repository ignores a lot of hyperparameters. For example dropout etc. The absence of these parameters will hinder the further use of this work in scientific comparisons. So is it considered to add additional hyperparameters? Below is an example of FT-Transformer showing the hyperparameter space in the original paper and the version implemented in this repository.

For a more detailed comparison check out the original repository implementation.
