Add style for image when using useRichText

[andreyeurope]

Hi. First I want to thank you for the work you've done on this package.

Because of the known wrap bug, I have to use the rich text parser.
When using the rich text parser, the image is aligned in the center.
Could you add some parameter for custom styling the image from rich text parser and maybe onTap support as well?

P.S.: I could also do that and then create a pull request.

I'd be glad to work on that feature, but it will probably be much faster if you open a pull request for the feature, since I'm pretty busy.

Thank you for your work. This has been released in version 0.10.1.
