All the options that are particular to NoiseChisel are now explained
in the manual. Some of the options also underwent small corrections:

  - --minbfrac and --minnumfalse were moved under the Input category
    from the detection category in the output of --help. This was
    because these two options are used by the detection as well as
    segmentation steps.

  - --checkthresh was renamed to --checkthreshold. The user can even
    use --checkt to get the functionality. It is just more clear like
    this.

  - --numerosion was changed to --erode. This makes it much more
    easier and comparable to the --opening and --dilate options.
