title: ngx-bootstrap datepicker - disable specific days
body: <p>I am using v2.0.1 of ngx-bootstrap in my project.
  I am trying to configure the <strong>datepicker</strong> to disable certain days.
  The config option is dayDisabled.
  This feature was implemented in v2.0.0 of ngx-bootstrap.

  The way I am implementing it is not picking it up.</p>
  
  <pre><code>&lt;div class="row"&gt;
    &lt;div class="col-xs-12 col-12 col-md-4 form-group"&gt;
        &lt;input
          class="form-control"
          placeholder="Datepicker"
          bsDatepicker
          [bsConfig]="{ dayDisabled: '[0,1,2,3]', containerClass: 'theme-red' }"&gt;
    &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
