BloodMNIST statistics and PCA

BloodMNIST (64x64 resolution) mean (mean_reshaped.npy) and standard deviation (std_reshaped.npy) calculated on the training set;

BloodMNIST's covariance matrix's (64x64 resolution) eigenvalues (eigenvalues.npy), the ratio of total variance explained by each principal component (eigenvalues_ratio.npy) and BloodMNIST's principal components (pc_matrix.npy) computed using the normalized training dataset.

These items were computed from the BloodMNIST dataset [1] and there used in [2].
