(hmi) QRCodeDecoder

[P-ict0]

After merge, merge also robot launch files PR and hero_bringup PR

Adds QR code reading functionality to hero as a wrapper for an HMI server.
Aimed for GPSR and EGPSR.

ToDo:

• Remove hardcoded 'hero' from topic list
• Read qr code x times to verify the data
• Check how much of the screen the qr code takes up (to not have false positives)
• Add maximum tries
• Add pyzbar to the dependencies
• Add to lauchfile
