True Positives, False Positives, True Negatives, False Negatives from 2 Matrices

Returns TP, FP, TN, FN given 2 matrices populated with 1's and 0's

- This simple function takes in 2 matrices of equal size populated with 1's and 0's and returns the number of True Positives, False Positives, True Negatives, False Negatives in order for precision and recall calculation
- 1st matrix is the true matrix
- 2nd matrix is the one populated from an algorithm used
- Returns error metrics based on a binary classification
