cmd app enforces a maximum "filter_speckle" of 16

[lucadalli]

The cmd app does not allow filter_speckle values greater than 16: thread 'main' panicked at 'Out of Range Error: Filter speckle is invalid at 20. It must be within [1,16].'

The web app allows much larger values (up to 126 on the web demo). Is this by design?

I think it's a mistake. I originally thought they are not the same metric. Turns out they are the same (size, not area).
