Separate station orientation position and rotation into separate options/values

Suggestion from https://www.youtube.com/watch?v=VAbBlOTnVLQ&lc=UgwNqQJoDKwEqGb4Pjd4AaABAg.ADEn3hLRqd5ADGb0eQFDSK:

i think the above-right, above-left and other "corner" options without the 45 degree angle would be a great addition (like in tennessine's metro designer). And maybe separate the position and rotation into two different options.

I'd need to do this in a way that ensures backwards compatibility (MDV4, perhaps), but this seems like a really good way to handle all of the various options you might want to do, and would reduce the menu clutter of having so many different orientation options.

As of writing, there's 10 station options. If I added Above Right, Above Left, Below Right, Below Left, that's 14 options to cycle through to find the one you want.

If broke them out into separate options, that goes from 10 or 14 to 8 label positions (Above, Above Right, Right, Below Right, Below, Below Left, Left, Above Left).

Then the label orientations are: No rotation, 90, or 45.
