Hyundai: support Elantra 2024

[sshane]

it's camera-SCC like the Kona EV 2022. Also, our recent understanding of SCC or RDR in the radar FW seems to describe if it sends SCC!

I've been too sick to drive a regular shift all week, but I did put about 6 hrs of driving in going to the store and such.

The only real issue is that it flashes and sounds a warning for "Communication Lagging: Take Control Immediately" about once every 75 minutes. This actually clears itself up after about two seconds so I've never actually had to take control, so I don't know how big of an issue this actually is.

The Hyundai still also has those annoying "Consider Taking a Coffee Break" warnings because it thinks I'm not paying attention whenever I use Comma AI to drive, but I don't think there's anything that can be done about that

Those and the lack of fingerprinting are the only issues.

All together it's finally usable for a 2024 Elantra.
