lua/autorun/gm-serialize.lua:

- Moved to lua/includes/modules, call require("gm-serialize") to use.

lua/includs/modules/gm-serialize.lua:
- Major refactor, moved to byte-based serialization after a month of
learning some stuff in a course. Beats out vON and pON in pON's provided
testing table.
- Final refactor and format change, any optimizations are welcome.
