Sometimes img src can be in attrs "data-src" instead of "src"

• html2text version: 2020.1.16
• Python version: 3.8.5

example url: https://jingyan.baidu.com/article/4dc40848741808c8d946f18a.html or WeChat articles.

I can not get all the images in such html. So I manually change the code of my local installed html2text and it works.

# original code in __init__.py: function handle_tag()
        if tag == "img" and start and not self.ignore_images:
            if "src" in attrs:
                assert attrs["src"] is not None
                if not self.images_to_alt:
                    attrs["href"] = attrs["src"]
                alt = attrs.get("alt") or self.default_image_alt

                # If we have images_with_size, write raw html including width,
                # height, and alt attributes
                if self.images_as_html or (
                    self.images_with_size and ("width" in attrs or "height" in attrs)
                ):
                    self.o("<img src='" + attrs["src"] + "' ")

# after change (add attrs["data-src"]):
        if tag == "img" and start and not self.ignore_images:
            if "src" in attrs or "data-src" in attrs:
                if "src" in attrs:
                    assert attrs["src"] is not None
                    img_src = attrs["src"]
                elif "data-src" in attrs:
                    assert attrs["data-src"] is not None
                    img_src = attrs["data-src"]
                if not self.images_to_alt:
                    attrs["href"] = img_src
                alt = attrs.get("alt") or self.default_image_alt

                # If we have images_with_size, write raw html including width,
                # height, and alt attributes
                if self.images_as_html or (
                    self.images_with_size and ("width" in attrs or "height" in attrs)
                ):
                    self.o("<img src='" + img_src + "' ")

I hope this can be considered in the future.
