feat: add Flask proxy app for cdn.jsdelivr.net

Browse source 
Introduce a simple Flask app that proxies requests to cdn.jsdelivr.net.
Includes basic routing for home and proxy endpoints, and a template
render for the home page explaining usage. Added Flask to
requirements.txt and updated .gitignore to exclude venv and __pycache__.

nobsdelivr is a simple proxy to cdn.jsdelivr.net. Use it to proxy your
requests to the CDN.
</p>
<hr class="my-4" />
<p>
To use the proxy, simply replace
<code>https://cdn.jsdelivr.net</code> with <code>{{ domain }}</code> in
the URL.
</p>
<p>Example:</p>
<code>{{ domain }}npm/bootstrap@5.1.3/dist/css/bootstrap.min.css</code>
</div>
<script src="/npm/bootstrap@5.1.3/dist/js/bootstrap.bundle.min.js"></script>
