Support for RichText Resolver

[simonarstam2]

As of now there is no implementation for a RichText resolver, it would be a nice feature to add.

What I think is most important is:

• Paragraphs
• Headlines (all levels)
• Bold, italic, strike, underscore
• Links
• Ordered lists, unordered lists
• Pictures
• Quotes

What is think is less important:

• Inline code
• Code block
• Horizontal rule
• Rendering of blocks (although a nice feature)

The JavaScript client got a similar feature:

Dear @simonarstamtesting2. Thank you for the suggestion. Yes, currently there's no RichText support at all in the library (we prefer Markdown).

It should not be too hard to implement (apart from the rendering of "inline blocks"). Are you interested in providing a PR, I'd be happy to review and merge.
