Add some a2x decoding fixes from upstream PR#5

PR: https://github.com/asciidoc/asciidoc-py3/pull/5

Commits:
6469317 Remove unnecessary decode in a2x (Matthew Peveler)
684913e Fix decoding of file that specifies encoding in header tag in a2x (Matthew Peveler)
8369a97 re-add --nonet option (Matthew Peveler)

These changes fix failures in building cgit's documentation (and
hopefully other similar decoding failures).
