API facade

[joan38]

Motivation

Currently the API is a bit scattered. Users need to import types from many packages and get exposed to the internal organisation of Orkestra.
That means if we move a type of package it would be a breaking change.

Proposed change

Create a package object that would contain type aliases to the main types needed.
Acting as a facade for the API users would just need, for simple usecases, to:

import tech.orkestra._
