Print hex in Debug for Sequence 

Printing the `Sequence` as a decimal is not super useful when debugging,
print it in hex instead.

Using code:

        let seq = Sequence::from_consensus(0xFFFFFFFF);
        println!("sequence: {:?}", seq);

Before applying this patch we get:

        sequence: Sequence(4294967295)

And after applying we get:

        sequence: Sequence(0xffffffff)
