implements S7HMux
```
Implementation of a multiplexing channel, from an embedded channel to two possible TCP connections, primary and secondary. The objective is to allow connections to individual systems with a two CP (PN CPUs, CP343-1, CP443-1 or similar), or H-type systems (S7-400H or S7-1500H). The user App must be in charge of restoring the requests or subscriptions that it is requesting.
