In-Memory Session Storage

This package implements the SessionStorage interface to work with an in-memory storage table.

``js
import {shopifyApp} from '@shopify/shopify-app-express';
import {MemorySessionStorage} from '@shopify/shopify-app-session-storage-memory';

const shopify = shopifyApp({
sessionStorage: new MemorySessionStorage(),
// ...
});
`

> Note: :warning: This session storage model is for local development only, to make it easier for developers to get started.
> It will delete all sessions if the app process gets restarted or redeployed, and is not meant for production use.
> For persistent storage, use one of the other options (see relevant section above for instructions).

If you prefer to use your own implementation of a session storage mechanism that is compatible with the @shopify/shopify-app-express` package, see the implementing session storage guide.
