Noise corrected Galar dataset splits

Based on the Video Capsule Endoscopy Galar dataset published by Le Floch et al. in 2025, new splits are generated (as described in https://arxiv.org/abs/2602.06938) and provided here. These contain the dataset splits with the proposed correction (split_corrected_train_val) or filtering (split_filtered_train_val) applied as well as a file (all_data_corrected_filtered_without_splits) labeling each sample in the entire Galar dataset as anomalous or healthy, as determined by our annotation pipeline
