Title: PA: I-476 Exit #31 changes

Ok, recently, new ramps opened there for PA-63 that are EZ-Pass only which are completely separate from the current '31' point on I-476.  These new ramps are a direct connection to PA-63, unlike the current trumpet interchange (which had no changes made to it).  Because of the changes, we now will have a problem with PA-63's file because of possibly needing to either recenter the current 'I-476' label, or add in a new one.  The changes needed to be made to I-476 are cut and dry thankfully.

I recommend the following changes be made and I'll do them if nobody thinks there's a problem here.

I-476 changes:
new -> 31A (point to be centered directly ontop of PA-63.
31 -> 31B (with 31 hidden)

PA-63 changes:
(option 1): Recenter the current 'I-476' point onto the new '31A' location.
(option 2): Relabel the current 'I-476' point to 'I-476(31B)' (while keeping 'I-476' as a hidden label for it), and add a new point at the center of the '31A' interchange and label it as 'I-476(31A)'.

I'm thinking Option 2 might be the best for PA-63, but want opinions.  You can see the new ramps in Google's Satellite imagery, so you get a good idea of what's happening here.

I prefer Option 1.

Any other comments before I do this (leaning towards option 1 for PA-63 now).

I also prefer option 1.

Fix for this has been submitted as Pull Request #1038 (https://github.com/TravelMapping/HighwayData/pull/1038) using 'Option 1' for PA-63.

Sorry for the late-coming, but a strong argument could be made that this is a single interchange.  What was changed for PA 63 is fine.  But instead of two separate points on the I-476 list, the "31" point should have simply been moved to the PA 63 overpass and left it at that.

It's wibbly-wobbly, to be sure. I decided I was fine with it being two points, for an "interchange and a half". :)
I did take froggie's approach recently, with the reconfiguration of KS I-70 224(KT) (https://github.com/TravelMapping/HighwayData/commit/371a7cc0e2885565484e39380ca578977746a113).

Well, 31 was in use, which was one of the main reasons I had in my mind to keep the location as is since that interchange didn't move at all.  Plus, SB I-476 didn't get a new offramp like the NB side did.  So, you could say they are effectively two different interchanges.

With Yakra's example, that interchange was completely reconfigured and all the I-70 EB ramps were moved to a new location, justifying the relocation of the point wholesale to it's new location.  With the I-476 one, you can say it was an entirely new 'partial' interchange that was added for I-476, as none of the original ramps were removed.

Semantics.  I don't think it would have killed much to leave it as a single 31 point and move it to the overpass (0.2mi is effectively a rounding error for most people's lists).  Functionally, it's a single interchange, and we've had single points for much larger interchange footprints than this.

Ah, but it so often does just come down to semantics in this project though...
I might have done it with one point (or not?), but I'm fine with two.
