check version1 pretrained model from original paper

[mateuszwyszynski]

In the original version of the code, two pretrained models were shared under this link: version1 and version2. For the first version there is no config file, so for now I was able to check only how the second version works. Maybe one can extract the configuration of the first version from the model checkpoint and then we will be able to test the first version as well.
