Update pip to code at head

Assigning the dota2 subprocess' stdout to subprocess.PIPE blocks all console logging. When stdout == subprocess.PIPE, the dota2 process will not write anything to its console logs, regardless of the value of the -console or -con_logfile or dota2 flags. My guess is that since nothing is consuming that pipe, the dota2 console ends up being blocked since it can't write anything to a pipe that isn't being consumed.

Tested via manual editing of the source code in my local workspace to verify what was happening.

Sorry, this turned out to be a red herring. The real issue is that the version on pip (https://pypi.org/project/dotaservice/0.3.9/) doesn't have commit 733db26. Is there any way to get an updated version on pip?
