The patents have now expired everywhere in North America and Europe.

Note that this is not dumping the raw AMR call audio stream, which is impossible on Android. The audio goes from AMR -> PCM -> AMR so the output is a lossy reencoding. Users who want lossless recordings should stick with FLAC or WAV.

Closes: #264
