Builds the :content a post is created or updated with.
FoPost.Posts.create/2 accepts any of these shapes and normalises them for you, so
reach for this module only when you want to build the blocks yourself:
FoPost.Content.text("One post")
FoPost.Content.thread(["First", "Second", "Third"])A block is a map of text plus an optional list of media, each item a map of type
("image", "video", or "gif"), name, and url.
