*StateMachine Conversion

[christianheussy]

Current Limitation

Statig currently defines three types of state machines:

• UnInitializedStateMachine
• InitializedStateMachine
• StateMachine - This type employs lazy initialized.

Deserialization yields an UninitializedStateMachine, which can subsequently be transformed into an InitializedStateMachine via the init method. However, the StateMachine type, being lazily initialized, is predominantly used throughout the codebase and offers better readability. It would be beneficial to provide direct conversion methods to StateMachine from the other two types.

Proposed Solution

Implement the following conversions:

• From<InitializedStateMachine> for StateMachine
• From<UnInitializedStateMachine> for StateMachine
  • In this case, the initialized field within StateMachine should be set to false.
