[Feature request] Update porcupine version for use with macOS arm

[g3ar-v]

@KoljaB I wanted to know if updating porcupine is part of the plan. This updates porcupine to v3.0 which supports mac m series and allows you to create custom wake-words given you have an access key.
I also have a working forked repo which does this. If it appeals to you I can make a pull request.

Pvporcupine until 1.9.5 is free without need for an internet connection. Since 2.0 it needs subscription (payed service). This contradicts my open source philosophy.
