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

[Carter Bullard]

Hey Kevin,
We have implemented print formats for some fields, and it maybe that the bug is in that logic, its described in the ra man page.  Try printing the asn's with the  explicit format %d.  I'm not near the code so forgive my memory if this is not right, but try:

   ra -s +sas:6:%d

see if that changes anything.

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).
