Fix exporting of closewrite since Julia Base now exports it

Also clean up usages of startread, closeread, startwrite, closewrite to
quality to the IOExtras module. Also fix the websocket tests that were
hanging since echo.websocket.org doesn't exist anymore. I found pie
socket that offers a free websocket testing server if you sign up and
get an api key, so that's been added as a repository secret now. If
anyone wants the api key to run the tests on their local machine, I'm
happy to share.
