Add Used By section to README

[jrycw]

@dantownsend , I recently noticed that Lance is using this theme on their website. Do you think it would be beneficial to include a Used By section in the README to showcase the projects using our theme?

@jrycw That's a good idea.

Here are a couple of others I've seen:

• https://cyclonedds.io/docs/cyclonedds-python/latest/
• https://bitstring.readthedocs.io/en/stable/#

Would you like to create a PR?

I'll go ahead and close this issue as it has been addressed by #76.
