Add public node endpoints with payloads.

[EvieePy]

This adds public fetch endpoints to Node. Currently they are private, this makes them public.
These endpoints don't alter the Node or Players in anyway, so there should be no risk of internal mishaps.

In the future I can evaluate making the update endpoints public also.

Changes look good to me!
I personally cannot comment on the state of the documentation as I cannot build them locally right now to test, so if you're sure they are all good then this is good with me!
