Caption integration with pymdownx.blocks.caption extension

[joapuiib]

pymdownx.blocks.caption is a new extension that provides a markdown syntax to generate <figure> with captions.

![alt](url)
/// figure-caption
    attrs: {class: "glightbox-attribution"}
Attribution
///
/// figure-caption
    attrs: {class: "glightbox-description"}
Nested caption
///
/// figure-caption
    attrs: {class: "glightbox-title"}
Caption
///

will generate:

‌<figure id="__caption_1" class="glightbox-title">
‌<figure id="__caption_1_1" class="glightbox-description">
‌<figure id="__caption_1_1_1" class="glightbox-attribution">
<p><img alt="alt" href="url" /></p>
<figcaption>Attribution</figcaption>
</figure>
<figcaption>Nested caption</figcaption>
</figure>
<figcaption>Figure 1: Caption</figcaption>
</figure>

I see there's a Caption support in this plugin.

![Madeira, Portugal](../images/gallery/blueswen-madeira.jpeg){ data-title="Madeira, Portugal." data-description="Madeira, an autonomous region of Portugal, is an archipelago comprising 4 islands off the northwest coast of Africa. - Google" }

Would it be possible to integrate this plugin captions with the pymdownx.blocks.caption extension?

This extension provides a way of setting a class to <figure> elements. Maybe a class naming convention (similar to data-description) could be used to extract the information from the <figure> elements.
