Extend APCI services

[basilfx]

Description

This extends #519 to support more APCI services. Basically, this parses (or generates) other payloads for telegrams.

I've added two additional examples (example_info.py and example_restart.py) to demonstrate some new APCI services. The existings example_telegram_monitor.py should be able to parse telegrams with these APCI services.

Note that the KNX application layer specification defines when to send specific APCI services. For instance, UserMemoryRead should only be send in a point-to-point connection-oriented link (which is not supported by XKNX). But it is still possible to generate and send the payloads, e.g. for your own hardware :-)
