Ticket: OISF#4083

As warned by clippy 1.72.0

Update the Bitflags crate to the latest supported version. This fixes
up a new clippy warning:

error: &-masking with zero

    = note: `#[deny(clippy::bad_bit_mask)]` on by default
    = note: this error originates in the macro `__impl_bitflags` which comes from the expansion of the macro `bitflags` (in Nightly builds, run with -Z macro-backtrace for more info)

When comparing IPv6 addresses based on uint32_t chunks, one needs to
apply ntohl() conversion to the individual parts, otherwise on little
endian systems individual bytes are compared in the wrong order.
Avoid this all and leverage memcmp(), it'll short circuit on the first
differing byte and its return values tells us which address sorts lower.

Bug: OISF#6276

Commit e7c0f0a removed uses of atoi with a new number parsing
functions. This broke parsing ip-reputation data files that contained
trailing carriage returns as it was being included in the number
string to convert.

Bug: OISF#6243.
