We are trying to parse byte-string from Nokia ALU device accounting.

AV-pairs looks like:

Alc-Acct-O-Inprof-Octets-64 = 0x00030000000000000001

Yeah, they're pretty terrible.

We need to obtain second byte from Alc-Acct-O-Inprof-Octets-64 (this byte represents traffic-class number)

Also, we need last 8 bytes from the same pair (this counter represents bytes counter itself) ... How can we obtain this counters without using an rlm_perl or rlm_python for av-pair parsing?
