Switch node - wildcard option for routing

[Steve-Mcl]

@jbudd I agree (almost) entirely with what you are saying & why I have pretty much dropped this now.

The original request was for a MQTT-like topic filter which is not so easy in regex nor JSONata. Example...

@Steve-Mcl

e.g. to achieve a really simple topic filter of +/1/+/temperature in regex is ^[^\/\n]+\/1\/[^\/\n]+\/temperature$

example

But ultimately it was rejected so I made a subflow instead.
