feat: Moving to multi-module project architecture

This takes advantage of Golang workspaces: https://go.dev/doc/tutorial/workspaces

The idea is that every `plugin/*` is its own submodule, and they contain the strict dependencies needed, instead of having them in the root module.
This make the `spelunk/v2` root module extremely lean - almost no dependencies.

And yes, as this is a breaking change, pushes us towards a v2 release.
