PA: PA 23 Minor Point Errors east of Lancaster

[Markkos1992]

1.  The PA 23 point at Landis Valley Rd needs to be recentered to the relocated intersection.  Recently a FYA signal was put here but it does not show it in GSV.

2.  The point for New Holland Rd (NewHolRd) should actually be for Brimmer Ave.  Though this is fine as an alternate as it becomes New Holland Rd to the south.
