Update OBS Actions to use the Latest Websocket API

[Da-Boom]

With the latest version of OBS, obs-websocket was integrated into the OBS project as a whole. With the advent of the new 5.0 websocket protocol, this has introduced breaking changes. At the current time, its possible to install compatibility plugins in order to make the current obs-websocket 4 based Actions work again, but this may become impossible as its not guaranteed the compatibility library wont be abandoned in the future.

As a result, a revamp to the current OBS actions so they work properly with the latest spec for the OBS-websocket protocol is needed. It can also have the effect of simplifying the setup procedures wildly for anyone who uses or hopes to use the Stream-PI software
