Update branding

Is your feature request related to a problem? If so, please describe it.
json-quick doesn't have any meaningful branding. Its name is also not very memorable.

Describe the solution you'd like
json-quick should be renamed and rebranded.

Describe alternatives you've considered
Not rebranding would have some advantages (no change in repository URLs, etc.). However, json-quick just isn't a great name.
