Numeric identifier

Expression

String expression in Hex format that contains information about evaluation:

1. IsEnabled
2. EvalLeftValue
3. ConditionOperation (enum class ConditionOperation)
4. EvalRightValue
5. ConditionLogic (enum class ConditionLogic - NONE, AND, OR, XOR)

Evaluation of value consists of:

1. Constant
2. Worldstate Variable
3. Function
