trying to fix bug in final plot screen
ie. when nlayers is a multiple nc*nr
fixed subsetting problems by using Z dimension instead of revising sceneinfo

But there is still a problem with the plotting that needs to be fixed
plotting seems to be working ok now

...still needs to be further tested
resolved merge conflicts

but still not sure if tsChipsRGB is working 100% of the time (some strange plotting behaviour)

Merge branch 'fix-tsChips' into develop

Conflicts:
	R/tsChips.R
	R/tsChipsRGB.R
