Go library for URL validation and verification (library)

 url-verifier is a Go library for URL validation and verification: does this URL
 actually work?
 .
 Features:
   - URL Validation: validates whether a string is a valid URL.
   - Different Validation Types: validates whether the URL is valid according
     to a "human" definition of a correct URL, strict compliance with RFC3986
     (Uniform Resource Identifier (URI): Generic Syntax), and/or compliance with
     RFC3986 with the addition of a schema e.g. HTTPS.
   - Reachability: verifies whether the URL is actually reachable via an HTTP
     GET request and provides the status code returned.
