Eleventy Transform: ignore <img> inside of <picture> with other sources.

Or better: optimize and replace instances of <picture>.

Hey @zachleat !

Could you please tell me if this will help solve the following problem:

Often, I need to have a picture element in advance to apply a class to it.

.intro__picture {}

But this leads to a nested picture element appearing in the markup after the plugin has processed it.

<picture class="intro__picture"> <!-- My picture element -->
  <picture> <!-- The picture element from 11ty plugin -->
    <img />
  </picture>
</picture>

As a result, I have to remove the picture element I wrote and rely on the one created by the plugin after it processes. However, writing styles in this case becomes difficult.

.intro picture {}

Sometimes, there is more than one image in a block, which means additional wrappers need to be created, etc. It seems to me that it would be good if the picture element that appears after the plugin is processed either took all the attributes from the current picture element, or if the plugin completely ignored creating a picture element if one already exists in the markup.

Just bumping this up as I'm having the same issue @what1s1ove is.

If there was a way to add classes to the <picture>s generated from the Transform Plugin, it would make the usability of the plugin that much better.

I know this plugin does something similar:

Perhaps we can add a hoistClass option to the image config? Or maybe an attribute override, similar to eleventy:widths or eleventy:formats? Or both?
