Instance Configuration

FSM instance is configured by defining Config type, and passing it into hfsm2::MachineT<TConfig>:
```
using Config = hfsm2::Config;
using M = hfsm2::MachineT<Config>;
```

Multiple hfsm2::Config sub-types can be combined together:

using Config = hfsm2::Config
                    ::ContextT<TC>
                    ::ManualActivation
                    ::PayloadT<TP>;
