§Random constants

Allows you to insert random constants into your code that will be auto-generated at compile time. A new value will be generated every time the relevent file is re-built.

§Example

use const_random::const_random  ;
const MY_RANDOM_NUMBER: u32 = const_random!(u32);
const MY_RANDOM_BYTES: [u8; 32] = const_random!([u8; 32]);

The following types are supported u8, i8, u16, i16, u32, i32, u64, i64, u128, i128, usize, isize and [u8; N].
