feat(client): introduce komorebi-client crate

This commit introduces the komorebi-client library crate for other Rust
applications to interact with a running instance of komorebi over Unix
Domain Sockets.

Currently the crate re-exports everything one might find in the
komorebi::State struct and everything that is publicly exposed in
komorebi-core.

Public types and methods are still lacking documentation, and this crate
should not be published on crates.io until this is no longer the case.
