FABADA can segfault when fit is bad

Description

When running FABADA with stupid limits for the chain length and max iterations the minimizer can segfault when generating the reduced chain (reducing the number of chain points by a factor of StepsBetweenValues).

The times I've managed to get this to happen the MaxIteration limit was hit and the ChainLength was significantly larger then MaxIterations.

You would never actually run FABADA with this setup but reducing MaxIterations is usually how I speed up testing.
