BGP Community Parser / Formatter

Convert a BGP standard community between ASN:VALUE and its raw 32-bit decimal/hex form, recognize well-known communities (NO_EXPORT, etc.), and validate large communities. Extended communities (RFC 4360) use a different, more complex wire format and aren't covered here.
