Nora endian

Yet another crate to deal with endianness, though focused on simplicity

Example

```rust use nora_endian::u32le;

let flags = u32le::from(1234); let index = u32le::from(0);

// Easy operations on & comparisons between le/be and native types if flags & 1 == 0 { // ... }

let indexplusoneu32: u32 = 1 + index; let indexplusoneu32le: u32le = index + 1; ```
