The following request will be correctly passed to a server:
amfora [::1]
amfora gemini://[::1]

The following will not be correctly passed to a server:

• amfora [::1]:1965 --> Request will be --> gemini://::1/ Should be gemini://[::1]/
• amfora gemini://[::1]:1965 --> Request will be --> gemini://::1/ Should be gemini://[::1]/
• amfora [2a02:8050:b18d:9b00:2d8:61ff:fedd:20ff]:1965 --> Parse "gemini://2a02:8050:b18d:9b00:2d8:61ff:fedd:20ff/": invalid port ":20ff" after host. --> Request will not be propagated to serer

Expected behavior:
Correct handling of URIs and passing according to RFC 3986 (e.g.: https://tools.ietf.org/html/rfc3986#section-3.2.2) , especially with respect to the [ $IPv6 ]:$PORT syntax.

   A host identified by an Internet Protocol literal address, version 6
   [RFC3513] or later, is distinguished by enclosing the IP literal
   within square brackets ("[" and "]").  This is the only place where
   square bracket characters are allowed in the URI syntax.

Thank you very much for work, i really enjoy amfora.
