Enhancement, provide a command to continuously read and compare typeID(s) values.

Typical usage would be to try and find what a given switch/setting affects.

Something like:

monitor <device ID> <type ID(s)>

This would poll the device and type at second intervals and print the difference between polls if any of the values changed. Ideally would be great if a range of type ID's could be specified.

I've tought about this. A fixed interval will flood the tx-queue completl if the we need to read more parts of a telegram. I've made a test with a single telegram, reading all parts, store them and after last part put the next read command to end of queue. Works, but makes a lot of traffic on the bus. I also don't see any advantage of this. It's much easier to read a telegram, make the change on boiler/thermostat/controller and send a read again. Then we are sure that the change has happend and we have to compare only 2 reads. Nevertheless, try out, this bin and have the telnet-monitor command: EMS-ESP-3_4_0b18dev-ESP32.zip and here is a test log, showing the the output with ww temperature changes and (with log debug) the bus-traffic: 20220520_111345_EMS.log
