Reddit's public JSON endpoint returns 403 to requests carrying the
generic User-Agent and minimal header set urllib defaults to, while
matching curl requests succeed. Switch to a current-Chrome User-Agent
and add Accept-Language / Accept-Encoding / Connection headers so the
fingerprint matches a normal browser. Reddit now serves gzip when
Accept-Encoding includes it, so decompress the body before JSON parse.
Update the user-agent assertion in tests/test_reddit_public.py to match
the new browser-like string. Closes#199.
