Increase the kMaxIterations limit (#1668)

* Increase the kMaxIterations limit This fixes #1663. Note that as a result of this change, the columns in the console output can become misaligned if the actual iteration count is too high. This will be dealt with in a separate commit. * Fix failing test on Windows * Fix formatting --------- Co-authored-by: dominic <[email protected]>
