 * <p>Parameters for the benchmark are:
 *
 * <ul>
 *   <li>size: the length of the byte array to hash
 *   <li>whereToDiffer: where in the array the bytes should differ
 *   <li>equalsImpl: which implementation of array equality to use
 * </ul>
 *
 * <p><b>Important note:</b> the primary goal of this benchmark is to ensure that varying {@code
