Fix Python 3 compatibility for newer Twisted (#73)

* Fix Python 3 compatibility: simplify putChild and add reactor to HttpbService

Drop Python 2 support: replace the version-conditional double putChild
call with a single b'http-bind' bytes call, and remove the now-unused
sys import. Add self.reactor to HttpbService so newer Twisted (22+)
can access site.reactor in server.Session.__init__.

* Replace Travis CI with GitHub Actions

Travis CI is no longer functional for this repo. Replace it with a
GitHub Actions workflow that tests on Python 3.10-3.13 against both
the latest Twisted release and Twisted trunk, with and without
PyOpenSSL.
