ZAF: Assorted issues with national highways

[shiggins]

N1:
VanRieSt: Should be R323.
N1 has been rerouted onto a new bypass around Musina.
N2:
R56_W: A new interchange has been built, so the point will have to moved.
IanWooSt: Should be MthByp.
N4Sch:
Geo: Should be Goe.
N9:
The R56 point is centered on the overpass, not the single access road between the two routes.
N11:
R517: It seems R542 has been extended along what OSM labels as R517 between N11 and Breyten. If we consider this an unsigned concurrency, then the point should be R542_E.
N14:
The point R372 does not seem to be R372. While the RDDA says R372 ends at N14 in Kagung, it is instead signed from R31. The sign on N14 which previously existed at this point did not mention R372.

N1 is missing a point at exit 391. While this is mainly for a service plaza, the southwestbound lanes do have the opportunity to exit onto R101.

N2 is missing a point at R102_E between 43(W) and M153 in Somerset West.

I can see that these issues have been fixed on Github for a few days and announced on the updates page tonight, but they were not actually fixed with tonight's site update.
