Simple, fast, no-dependency cache for async calls.

```js

import { createCache } from '@leichtgewicht/async-cache'

const cache = createCache({

  resolver: async (key) => {

    // load data or do something else to get the value for the key

    return value

  },

  maxSize: 1000, // max amount of keys cached at the same time

  maxAgeMs: 1000 // (optional) maxAge for a result before refetching

})

const result = await cache.get('key') // load the key, if present in cache and not expired, will return previous value

result // result as provided by the async resolver

```
