A simple Deno LRU cache utilities.

## Example

```typescript

import { create, LRU } from "https://deno.land/x/dcache/mod.ts";

// Create a LRU with cap 3.

const lru: LRU = create(3);

// Set key/value

lru.set("foo", 42);

lru.set("bar", 1024, 1000); // with 1s ttl

lru.set("baz", 2048);

console.log(lru.get("foo")); // print: 42

console.log(lru.get("bar")); // print: 1024

await new Promise((res) => setTimeout(res, 1000)); // sleep 1s

console.log(lru.has("bar")); // print: false

lru.set("aaa", 777);

lru.set("bbb", 888);

// Discards the least recently used item which is "baz"

console.log(lru.get("baz")); // print: undefined

console.log([...lru.keys()].join(",")); // print: bbb,aaa,foo

lru.forEach((v, k) => console.log(`${k}=${v}`));

// print:

// bbb=888

// aaa=777

// foo=42
