Bugfix: remove ghost pixels when changing segment options

Browse Source 
... transpose, mirror, reverse, grouping, spacing, size

* unlike AC WLED, when calling seg.fill(BLACK) from webserver context this usually has no effect --> added  markForBlank() that shedules segment blanking at the next drawing cycle
* fill previous segment with black when size, grouping or spacing changes
