map-swipe: Map-swipe layers not rendering correctly

[FilipLeitner]

Bug

Describe the bug
Layers are not rendering correctly when moved around the map-swipe options (full, left,right) as a result of update being only buffered

hslayers-ng/projects/hslayers/components/map-swipe/map-swipe.service.ts

Lines 84 to 86 in 19f2474

	buffer(
	this.hsLayoutService.mainpanel$.pipe(filter((p) => p === 'mapSwipe')),
	),

We should just proceed with stream in case layerManagerUpadate is fired while mapSwipe is active eg. updating layer states. This should fix the messy behavior or layer rendering incorrectly

Expected behavior
Layer rendering correctly eg. according to the assigned swipeside
