Docker support

Here's a docker setup for the web demo using the latest CUDA 12.4 with CuDNN 8.

Needs additional testing of all features if we are going to go with the updates in the requirements*.txt files. But this is a start.

Great, thank you for this. Only updating pvporcupine==1.9.5 to pvporcupine==3.0.2 raises issues for me: Up to version 1.9.5, it was free and didn't require an internet connection. From version 2.0.0, it introduced a licensing model requiring internet for verification and potentially a paid subscription. Thus, version 1.9.5 is the last free, fully offline version.

@KoljaB Thanks for the clarification. I've updated this to revert to 1.9.5.
