NC: NC 54 Minor Point Errors

[Markkos1992]

(From east to west)

1. Maybe add a point at either Cary Pkwy, Morrisville Pkwy, and Weston Pkwy.
2. AviPky should be changed to AviPkwy.
3. WMainSt should be MainSt.
4. Is it doable to replace GreRd with a point at Bethel-Hickory Grove Church Rd (BGChuRd)?
5. I do not see a viable alternative for WagLn.

EDIT: Maybe add Edwards Mill Rd or the Hillsborough St connector to Western Blvd as well.
