Add known HubProperties

[tthiery]

• Add Hub constructor argument (is filled automatically if not set)
• Query hub properties by known properties instead of static array
• Adjusted TechnicMediumHub and TwoPortHub

Closes #120 non-breaking

@vuurbeving can you review this? This will help with #119

That was quick 👍

Also, code looks good. I'm ok with merging this

I can check whether HardwareNetworkFamily property works for the twoporthub if I have some time.
