v3 install : no noise

[virmaior]

First off, thanks for this amazing work.

I was able to install wyzehacks on a v3 using ./remote_install.sh . After that, I didn't know two things:

1. that the install had succeeded
2. that the default password for a v3 is WYom2020

For 1, the log shows:
`+ play_sound /tmp/Upgrade/install_snd/finished.wav 50
/tmp/wyze_hack/install/main.sh: line 1: can't create /sys/class/gpio/gpio63/value: nonexistent directory

• echo 1
• /tmp/wyze_hack/install/bin/audioplay /tmp/Upgrade/install_snd/finished.wav 50
  /tmp/wyze_hack/install/main.sh: line 1: can't create /sys/class/gpio/gpio63/value: nonexistent directory`

There is currently a known issue with V3 cams that doesn’t allow audio play in the user space, which is what most hacks use. There should be no problem with V2
