Adopt hcxtools' (and hashcat's) new unified WPA input line format

See https://github.com/hashcat/hashcat/issues/1816#issuecomment-566546059

The new format is:

SIGNATURE*TYPE*PMKID/MIC*MACAP*MACSTA*ESSID*ANONCE*EAPOL*MESSAGEPAIR

Some notes:

• SIGNATURE = "WPA"
• TYPE = 01 for PMKID, 02 for EAPOL, others to follow
• PMKID/MIC = PMKID if TYPE==01, MIC if TYPE==02
• MACAP = MAC of AP
• MACSTA = MAC of station
• ESSID = ESSID
• ANONCE = ANONCE
• EAPOL = EAPOL (SNONCE is in here)
• MESSAGEPAIR = Bitmask:

0: MP info (https://hashcat.net/wiki/doku.php?id=hccapx)
1: MP info (https://hashcat.net/wiki/doku.php?id=hccapx)
2: MP info (https://hashcat.net/wiki/doku.php?id=hccapx)
3: x (unused)
4: ap-less attack (set to 1) - no nonce-error-corrections necessary
5: LE router detected (set to 1) - nonce-error-corrections only for LE necessary
6: BE router detected (set to 1) - nonce-error-corrections only for BE necessary
7: not replaycount checked (set to 1) - replaycount not checked, nonce-error-corrections definitely necessary

All fields are encoded in hex except SIGNATURE.

This is a great improvement to our old hack of simply Base-64 encoding the (deprecated) hccap struct.

A corresponding pot line in JtR will only contain ESSID and calculated PMK, something like

WPA*00*PMK***ESSID***:password

That is: TYPE is set to 00, next field is PMK and all other fields but ESSID are empty.
