[6-8hrs] Create a "Figure" streamfield block

[nmorduch]

• [1hr] Create block
• [1hr] Should also have sensible size options for images
• [2-3hr] Should be able to include multiple images/graphics side by side
  • [1hr] Extra credit: Dropdown to switch between multiple graphics, always on mobile, optional on bigger screens
• [2hr] Clean up (hide?) other image/graphic blocks

@chigby to make a new the model, FigureBlock should have:

• title (plain text)
• text (rich text. help text: "Displays below the title") (can we limit the length?)
• caption (rich text. help text: "Displays like a footer") (can we limit the length?)
• width (same options as on DatawrapperBlock)
• streamfield: Can have 0-8 (inclusive) of: CustomImageBlock, DatawrapperBlock, IframeBlock, DatavizBlock
• columns (number: 1-4 inclusive)

And it should be in the group 'Embeds'

I've made a FigureBlock with these fields.. I'm not what models to enable it for? Or is that something you were planning on doing?

@nmorduch Check out the draft PR here for the block code and a suuper basic template (and let me know if there are issues or enhancements you need to flesh out the html/css situation)
