A Rust library providing pretty hex dump.

A `simple_hex()` way renders one-line hex dump, a `pretty_hex()` way renders 
columned multi-line hex dump with addressing and ASCII representation.
A `config_hex()` way renders hex dump in specified format.

## Example of `simple_hex()`

```rust
use pretty_hex::*;

let v = vec![222, 173, 190, 239, 202, 254, 32, 24];
assert_eq!(simple_hex(&v), format!("{}", v.hex_dump()));

println!("{}", v.hex_dump());
```
Output: 

```text
de ad be ef  ca fe 20 18
```

## Example of `pretty_hex()`

```rust
use pretty_hex::*;

let v: &[u8] = &random::<[u8;30]>();
assert_eq!(pretty_hex(&v), format!("{:?}", v.hex_dump()));

println!("{:?}", v.hex_dump());
```

Output: 

```text
Length: 30 (0x1e) bytes
0000:   6b 4e 1a c3  af 03 d2 1e  7e 73 ba c8  bd 84 0f 83   kN......~s......
0010:   89 d5 cf 90  23 67 4b 48  db b1 bc 35  bf ee         ....#gKH...5..
```

## Example of `config_hex()`
```rust
use pretty_hex::*;

let cfg = HexConfig {title: false, width: 8, group: 0, ..HexConfig::default() };

let v = &include_bytes!("data");
assert_eq!(config_hex(&v, cfg), format!("{:?}", v.hex_conf(cfg)));

println!("{:?}", v.hex_conf(cfg));
```
Output:

```text
0000:   6b 4e 1a c3 af 03 d2 1e   kN......
0008:   7e 73 ba c8 bd 84 0f 83   ~s......
0010:   89 d5 cf 90 23 67 4b 48   ....#gKH
0018:   db b1 bc 35 bf ee         ...5..
```
