/**
 * A storeSplit function allows you to apply a different payload between your cache store vs your other stores.
 *
 * It will let TypeScript know that you're trying to apply the type of whatever you pass to the `cache` key, even though your other stores might receive other values.
 *
 * ### Example Use Case
 * ```ts
 * import { storeSplit } from '@magnetarjs/utils'
 *
 * magnetar.collection('user').doc('1').merge({
 *   name: 'updated name',
 *   // ...
 *   dateUpdated: storeSplit({
 *     cache: new Date(),
 *     remote: serverTimestamp(),
 *   })
 * })
 * ```
