Changes
- not convert the complete merge image into RGB but rather
- export 1 separate image for each channel (active or not)
- it will add the SVG style tag and add mix-blend-mode: screen; value to allow visualizing the merge
- it will add the SVG style value display: none; to all channel that are not visible in Fiji. Those will be available in Inkscape but not visible at import
- in the Inkscape layer tab, you can now activate or deactivate for each composite group the individual channel (see below)
