Wraps an `&[u8]` slice to provide a kitchen sink worth of tools.

Useful for writing a binary format parser that needs to be reverse engineered as you go.

Mostly untested, so gauranteed to have off-by-one errors. :P

Enable the `debug` feature to add extra functions.

You should only enable the debug feature during development as it comes with a performance hit due to storing extra data in FancySlice.

```rust

use fancy_slice::FancySlice;

fn main() {

    let data = vec!(4, 1, 3);

    let fancy_slice = FancySlice::new(&data);

    assert_eq!(fancy_slice.u8(0), 4);

    assert_eq!(fancy_slice.u8(1), 1);

    assert_eq!(fancy_slice.u8(2), 3);

    assert_eq!(fancy_slice.u16_be(0), 0x0401);

    assert_eq!(fancy_slice.u16_be(1), 0x0103);

    let inner_fancy_slice = fancy_slice.relative_fancy_slice(1..);

    assert_eq!(inner_fancy_slice.u8(0), 1);

    assert_eq!(inner_fancy_slice.u8(1), 3);

    assert_eq!(inner_fancy_slice.u16_be(0), 0x0103);

}

```
