take out fscd, use paket to acquire it

[dsyme]

This takes out the core code-format and interpreter code and tests, including it via source inclusion for the moment.

See #302

@TimLariviere Just to mention that I still think Fabulous should include its own CLI tool, even if only a very thin packaging wrapper over the generic FSharp.Compiler.PortaCode functionality.

This is because the on-device interpreter in Fabulous.LiveUpdate needs to match the PortaCode data format being sent by the live update tool. It's much easier for these to be kept in sync if the Fabulous CLI version numbers match the Fabulous.LiveUpdate version numbers (and the Fabulous docs explain that this needs to be the case)

@dsyme Ok, I see.
Do we check at runtime if the version matches between the CLI and LiveUpdate?

I think we also need to update the docs to reflect the need to update the CLI when migrating to a new release.

No we don't, we should. I suppose that has to be in the info sent to the webhook

@TimLariviere This is ready

[dsyme]

@TimLariviere I've already made some interpreter improvements in FSharp.PortaCode which we should bring in, but we can do that bit by bit

Improvements to the interpreter are here: fsprojects/FSharp.Compiler.PortaCode#2
