title: angular calendar how to change language
body: <p>I'm working with <a href="https://mattlewis92.github.io/angular-calendar/#/i18n" rel="noreferrer">angular calendar</a>, by default the language is english, i want to change it to spanish.</p>
  
  <p>My issue is that the documentation is poor, even the stackblitz example only works with french, if i try with spanish code (es), or any other language code, the calendar doesn't show nothing at all.</p>
  
  <p>How i can change the names of the days &amp; months properly with angular calendar?</p>
