CellVoyager Z adjustment: support simultaneous acquisition

[imagejan]

In cases where, we acquire two channels within the same "action", we should not expect new auto-focus values in the TRACE log file.

There's various possible strategies to solve this:

• Don't reset the focus value, but simply take the last present one.
  • This might be error prone as we might assign wrong z values to images
• Strip the C0*.tif part from the filename, and create a mapping with the remaining part of the name only
  • This will require additional logic when merging the z positions with the files table
  • We still parse both filenames, so we have to decide whether we want to issue a false warning, or add logic to ignore subsequent images with the same partial filename
• Reset the Z value only at the beginning of a new "period", adding a new parsing step for BeginPeriod, assigning all images before that the same Z value

I prefer the last option, as it is minimal implementation effort, and (despite the additional parsed line) seems the "cleanest" approach.

This was fixed with #128 and improved #138.
