title: Aggregation query using Sequelize and SQLITE
body: <p>Using Sequelize and SQLite, and having a table like:</p>
  
  <pre><code>A | B
  a | 1
  b | 2
  c | 3
  </code></pre>
  
  <p>I would like to create a map using a query via Sequelize, giving the following result:</p>
  
  <pre><code>{
    a: 1,
    b: 2,
    c: 3
  }
  </code></pre>
  
  <p>How can I do that? I can do a <code>findAll</code> and then a <code>docs.reduce(...)</code>, but I would like to extract that directly from SQLite if possible.</p>
