optics correction upgrades
- dispersion vs quadrupole, only numeric . no linear dependence of dispersion to quad gradients
- reintroduce fit of dispersion with dipoles, use analytic formulas
- reintroduce sub-blocks of RM and average of fitted errors per block.
- set up a test case with fit of dispersion with BendingAngle errors only and quad for beta only.
