Resolve Qt6 TODO items, replace Median and BlockSizeManager

* Replaces the, only internaly used, implementation of template
  class Median with a fixed size none templated version.
* Replaces BlockSizeManager with an updated BlockSizeManager V2,
  but keeping the original name.
* adapt the auto-test to take the fixed size array into account
