Add SSDP boefje to find devices inside of a network

[Souf149]

Changes

Add a SSDP boefje that scans for machines / services on local networks. A perfect example of a boefje that might need #3299 as a feature.

Demo

QA notes

To simulate a SDDP server I did the following:

1. I ran docker compose exec -it boefje bash
2. Inside of this shell I then install ssdpy with pip install ssdpy
3. And then run python3 -c 'from ssdpy import SSDPServer;SSDPServer("cynalytics-server",proto="ipv4", device_type="my_device_type",location="http://145.131.253.241:8000/en/cyn/").serve_forever()' to start a sddp server inside of the boefje container.

Additional note

Code inside boefjes/boefjes/plugins/kat_ssdp/main.py needs to have the import statement moved to the top of the file, but because of #3582 this is not possible.
