reimplement gg

This is a better version of gg.  Initially it grew with flags directly
needed to the specific test cases I wanted to write, so it's ugly to use
but handy for tests.

This is a new and re-thought implementation that it is (hopefully)
easier to use both and "curl-like for gemini" but also for scripts and
tests cases.

One completely new feature is the proxying support with -P to send the
request to the given host.
