Add a workspace client module

[MrCreosote]

The purpose of this module is to allow for serving the workspace client jar out of jitpack.io, which can only serve 1 jar per module.

I figured this approach was better than making a separate repo and having to sync over the spec, make sure the github releases were equivalent & up to date, etc.

The drawback is the duplicate generated code, but a 2nd repo would have that drawback as well.

Everything in client/src is SDK generated

how to make sure generated code is up to date?

[MrCreosote]

./gradlew sdkCompile compiles the generated code for both the client and server subprojects

This seems like a clunky solution but if there aren't any alternatives...

[MrCreosote]

It's 100% clunky. It's just the least clunky option I'm aware of
