Using without http server

[user753]

I would like to use it in tests like this

const mementoClient = MementoClient({
  cacheDirectory: path.join(__dirname, '<path to cache directory>')
});
const response = await mementoClient.request({url: 'foo', requestHeaders: [], ...})

I believe it should work faster than requests through http
