feature request: log apci

[KomtGoed]

Hi there,

Great tool, thanks so much!
Exactly (almost :)) what I am looking for: I would like to build a simple KNX group monitor, logging ALL KNX telegrams to InfluxDB (v1.8), comparable to what's described here: https://knx-user-forum.de/forum/%C3%B6ffentlicher-bereich/knx-eib-forum/1389088-knx-node-for-node-red/page14. And then build a Grafana view on top.

One element that I would like to include in InfluxDB is the APCI type. I think I found it in knxnet.cpp (ct?) but I am lacking the C++ skills to adjust knx2influx.cpp.

Would that make sense to add for you as well?
