v0.3.0-rc1

What's Changed

This is a release-candidate, as this new feature is a major improvement and first tests are green.
That said, there's also a known issue #190, which violates the engine's invariant and thus likely some BPMN workflows might not work after un-marshalling.

• implemented Marshal & Un-Marshall support, see #12 (this is a new feature and tests are not fully completed)

Migration notes for breaking changes

New Initializer

Bpmn Engines are anonymous by default now, and shall be initialized by calling .New()
Example: replace bpmn_engine.New("name") with bpmn_engine.New()

Note: you might use .NewWithName("a name") to assign different names for each engine instance.
This might help in scenarios, where you e.g. assign one engine instance to a thread.

activity.LifecylceState and process_instance.State

Both are consolidated towards bpmn_engine.ActivityState, which you can simply use in the same manner.

Use Go Getter idiomatic

For some interfaces, the prior code looked like e.g. engine.GetName().
According to https://go.dev/doc/effective_go#Getters, this getter should better be written as engine.Name().
