Changes on reimplementation of changeformer

[cch-meiple]

Hi, thank you for your great work!

I am validating several change detection models with my data. However, when I experimented with the official code, the changeformer didn't learn properly, while the changeformer you provided did. I think there is a difference between learning rate and some augmentation, can you tell me what changed when you reimplemented it?

Thanks!
