EAE (EasyAudioEncoder) Support, arm64 images and bugfixes

We finally have EAE (EasyAudioEncoder) support!! #125
The feature can be turned off, in case of issues, by setting the Worker environment variable EAE_SUPPORT to "false".

Also solves #155 around permission denied errors on the /codecs directory when not mounting it from a volume.

Multi-arch images now target ARM64 as well
