Update hashcat mode with new rules

A number of other rules have been added to hashcat in the meantime: h, H, S, B, v.

BNX and vNX.

Here's what they do:

For BNX and "print0 -> hello`" my first guess was that B6N would add 0x30 (with some N) to the 6th char '0' (0x30) resulting in the backtick (0x60). But we can't represent a byte value of 0x30 (48) with our 0-9A-Z (0-36) so we'd need to prepare a variable n first. So I presume this is not quite it, or maybe the example shouldn't be "print0 -> hello`" but some other character in the end of the result string (it's not a very good example). They haven't updated the Hashcat wiki and the file in docs is a header with no examples so I can't tell.

Like us they support \xNN syntax though, so maybe it's simply B6\x30 ?

The issue lists five hashcat rules and references issue #5553, but names no John source file, entry point, or test. Read the existing rule support alongside that discussion and verify each rule's semantics against the linked Hashcat documentation. Done means the requested rules are supported with behavior matching the descriptions and verified coverage.
