Feature Request: Text color picker

[ebetabox]

For some use cases it would be interesting to have a text color picker.

iOS14 introduces a native color picker component that would simplify the development of this feature, and for prior versions another library could be used or for the time being just manual HEX color.

Maybe I could contribute with this one. What do you guys think?

This issue is similar to https://github.com/wordpress-mobile/AztecEditor-iOS/issues/1290.

The UI elements for picking a font color should be implemented by the client App (in our case the Example app, although adding that is secondary at this time).

For some more context: I think our format bar shouldn't really be part of Aztec in the long run.

@ebetabox I don't think this is prioritized because the Aztec editor is expected to be used inside of a client app which adds UI controls for whatever rich-text features it needs.
