Unclear default value for --skip option in itkimage2segimage documentation

[LennyN95]

The documentation for the --skip option of itkimage2segimage is enabled by default and, as such, suggests the text.
However, the default value (default: 0) is also documented, which would suggest the opposite.

dcmqi-guide/opening/cmd_tools/seg/itkimage2segimage.md

Line 11 in d6c7c37

(default: 0)

--skip
     Skip empty slices while encoding segmentation image. By default, empty
     slices will not be encoded, resulting in a smaller output file size.
     (default: 0)

Maybe the default was changed over time. The code suggests it is enabled by default:

Should test to confirm the actual behavior...
