4-byte ASN numbers being expressed as floating point numbers by ralabel

[Carter Bullard]

Hey Kevin,
Can you send your test.arg file so I can debug ??

Thanks to your helpful documentation, I was able for the first time to get ralabel to mark records with source and dest asn.  It is overall doing a beautiful job, but I noticed in my results a few records with funky asn numbers being reported by ralabel, in floating point decimal format for some reason.  It appears to be happening only with 6-digit ASNs (or more likely 4-byte ASNs).
