scouting: Add a debug CLI for the webserver

This CLI should let us debug the webserver easily. It simulates calls
that the web page can make. Create a JSON version of the flatbuffer
message you want to send and pass it as a file to the correct option
on the `cli` binary. There's nothing really implemented yet because
the webserver doesn't have a whole lot implemented either.
