Fine-tune on the bigearthnet dataset

[hubery1619]

It is an interesting work. Based on the paper description "On the BigEarthNet-S2 dataset, these foundation models
are fine-tuned using a 10% subset of the training data," Could you tell me how you set the fine-tuning training dataset with 10% for the BigEarthNet-S2 dataset in the code. Thanks so much.
