NC: US-52 exit numbers (between NC-66 & I-74)

[rickmastfan67]

With no change over to I-74 #'s in sight for quite a few years still, should we finally add the US-52 exit numbers to the file between "*NC66Con" & "I-74"?  Especially since we already have the exit numbers on US-52 between 84 & 116 in the file.

Also, on a side note south of the former NC-66 interchange.

SprSt -> 108 or 108A (would need updated in US-311 & NC-8 too)
WauSt -> 108A or 108A_A (would need updated in US-311 & NC-8 too)
NOTE: those are the best solutions I can think of for this interesting quirk due to the split interchange ramps.

As for these two closed interchanges, since they did have #'ing posted before they were closed, I think it's safe to convert them as well instead of using the name of the road for the closed interchange.
*StaDr -> *108C (would need updated in US-311 & NC-8 too)
*4thSt -> *110A (would need updated in US-311 & NC-8 too)
