Provide real-time data to backend

[Hornwitser]

Feature overview
Name: real-time-scoring
TL;DR: Send progress and partial scores during the game to the backend

Details
The Web interface currently work in progress would benefit from being able to display in real time things like lap times, positions, scores, team progress, etc. For this to work it needs to have this data sent to it.

Possible methods
Basic idea is write files with updates as they happen and have the Node.js backend forward it to the Node.js server.
