title: How can I access state of another slice in redux with redux-toolkit?
body: <p>In my Redux store I have multiple slices and I would like to access the <code>lang</code> state of the settingsSlice inside the speciesSlice.</p>
  <p>Here is a code sample of my slices:</p>
  <pre class="lang-js prettyprint-override"><code>const settingsSlice = createSlice({
    name: 'settings',
    initialState: { lang: 'en', theme: 'dark' },
    reducers: {
      ...
    },
  });
  
  const speciesSlice = createSlice({
    name: 'species',
    initialState: data[`vds-list-${HERE I WANT TO USE THE &quot;lang&quot; STATE OF THE SETTINGSSLICE}`],
    reducers: {
      ...
    },
  });
  </code></pre>
  <p>Thus far I haven't found a solution so maybe it's just not possible?</p>
  <p>I could just use one slice with all of the state inside of there, but I'd really like to separate different parts of the state in different slices.</p>
