Versioning

[bladyjoker]

LambdaBuffers should adopt a versioning scheme for the lbf schemas, frontend/compiled, codegen modules, runtime libraries, and the Nix packaging tools.

TODO:

• Settle on a versioning scheme and document it
• Figure out the versioning strategy for various parts (what changes are safe, compatible with previous versions, and which are breaking etc)
  • LB Frontend, mostly syntax and module system related.
  • LB Compiler, has a Protobuf API, this should be central to this.
  • LB Codegen, has a Protobuf API, this should be central to this, but also the outputted code might affect users too.
  • Runtime libraries for Prelude and Plutus
• Introduce CHANGELOG

Before we start releasing the tools and publishing packages, we must have this sorted out.
