Call to undefined when scanning SSLv2

[carwyn]

When scanning a host with SSLv2 enabled (scanning for DROWN as it happens):

Traceback (most recent call last):
  File "./TLScan.py", line 838, in <module>
    main()
  File "./TLScan.py", line 817, in main
    processTarget(target)

  File "./TLScan.py", line 713, in enumCiphers
    for cipher in chunks(cipher_spec, 3):
NameError: global name 'chunks' is not defined
