Nim-Libravatar

Libravatar library for Nim, Gravatar alternative. Libravatar is an open source federated avatar api and service.

• Federation supported passing baseUrl, DNS server discovery is up to you if you want to, Pull Request welcome.
• 404 wont return 404, but a default image, use default="404" for a HTTP 404 Error.
• Uses func so is Side Effects Free, works with Async & MultiSync.
• runnableExamples included, Self-Documented, NEP-1 Ok.
