Jump Consistent Hash algorithm

Jump Consistent Hashing is a fast, minimal memory, consistent hash algorithm. In comparison to the algorithm of Karger et al., jump consistent hash requires no storage, is faster, and does a better job of evenly dividing the key space among the buckets and of evenly dividing the workload when the number of buckets changes.

Usage

```rust use std::collections::hash_map::DefaultHasher; use std::hash::{Hash, Hasher}; use jumpch::JumpHasher;

fn main () { let mut hasher: JumpHasher = JumpHasher::new(1000);

"test".hash(&mut hasher);

assert_eq!(hasher.finish(), 677)

} ```

```rust use jumpch::hash;

fn main () { assert_eq!(hash(123456, 1000), 176) } ```
