Check if performance can be increased for adjustment classes with new Hipparchus 1.7 differentiation classes
Hipparchus 1.7 (used by Orekit 10.2) added several new differentiation classes to handle simpler cases (univariate derivatives at orders 1 and 2 and gradients) with less overhead than the existing DerivativeStructure.
One must check if the new classes can be used in order to improve performance in the adjustment package.
