implement oyCMMFilter_GetNext_f()

oyraFilter_ImageChannelRun The "channel" option is build of channel fields. It contains the output section in one text string each in squared brackets: "[a|b|c]". Each channel is separated by pipe sign '|' and can contain the channel symbol or a fill value. -1 indicates the module shall select a appropriate fill value. The counting of channels starts from a and ends with z, covering the range of ASCII a-z. A special case is a "" no op signature. Use it for pass through.

With the above syntax it is possible to add or remove channels or simply switch channels of.

switch the second and thierd channels of: ["a", -1, -1]

swap first with thierd channel: ["c", "b". "a"]

duplicate the second channel and skip the first and possible the c and more source channels: ["b", "b"]

Note: changing the channel count might require a new ICC profile for the output image. Please setup the graph accordingly.
