Add build instructions, bump SDK version to v143, and add CI/CD

It also enables dll load for Episode 1.

It would be great to add a CI/CD workflow so we don't have to update the "UpdateServer" in the repo.

Added CI/CD just to see that it builds

I've pushed a new commit to address some missing binaries.
Build instructions for Windows are as simple as hitting Build in VS.

Typically this was just compiled directly through Visual Studio, so that should still hold true.

Also, I did some investigation and found that my repositories are missing the binaries detours requires... not sure if I did that intentionally or not. I'll address that soon by linking in my DLLShared repository as a submodule.

Might be a good idea to hold off including build instructions, at least in this PR. Those can be added once there's a finalized solution.

Merged updates, it is still able to compile on my PC with msbuild /p:Platform=x86 /p:Configuration=Release /t:Rebuild which is good.
