Request: LoadingBar Component

[Vehmloewff]

This would be a group of svg based loading bars.

The usage would probably look like this:

<LoadingBar
	value={50}
	preset="line"

	backgroundWidth={10}
	backgroundCorners={0}
	foregroundWidth={20}
	foregroundCorners={0}
	backgroundColor="var(--loading-bar-background)"
	foregroundColor="var(--loading-bar-foreground)"

	showLabel={true}
	showUnits={true}
	units="%"
	labelColor="var(--loading-bar-label)"
	unitsColor="var(--loading-bar-units)"

	borderWidth={20}
	borderColor="var(--loading-bar-border)"
/>
<!-- preset values: `line`, `circle`, `fan`, `bubble` -->
