Feature request: Schematic net label "in-line" rendering

[frmdstryr]

It would be nice if there was an "in-line" label orientation. When adding a label where rotating it looks awkward I often add 2 labels and cut the line between.

The request would be to render something like this (just without the vertical lines) if the net line goes through the label.

There are provisions for net labels without the flag decoration:

horizon/src/schematic/net_label.hpp

Lines 23 to 24 in 0ce0e68

	enum class Style { PLAIN, FLAG };
	Style style = Style::FLAG;

I think the best way forward is implementing proper support for them.
