Update G-Sheets script to parse JSON/msgPack docs

[Cogswatch]

Is your feature request related to a problem? Please describe.
We are currently deserializing then reincoding data into a specific format to be parsed sheet side. Considering that a majority of web protocols already support JSON, it would make sense to conform with the standard used both internally and externally for client and server side operation.

Describe the solution you'd like
Re-write the G-sheets script to parse JSON and msgPack.

Describe alternatives you've considered
Continuing to do things this way, which while not a bad idea, is far from ideal.
