Wanted change

mStream uses a binary for it's p2p feature (the binary is built and hosted in a repo I own). Right now there is a script that downloads the binary after booting up the server, but some environments block it from being downloaded. I have made PR that makes this build change:

#37

Reason for change

See above

Proposed code change
