AudioFile does not support mp3

[ftnext]

Thanks to #778, I learned that AudioFile does not support mp3. (related issues: #475, #704)
It may be a good idea to think about a feature extension that supports mp3 files. (related PR: #507)

Steps to reproduce

$ ffmpeg -i tests/english.wav -vn -ac 2 -ar 44100 -ab 256k -acodec libmp3lame -f mp3 english.mp3

>>> import speech_recognition as sr
>>> with sr.AudioFile("tests/english.wav") as source:
...   ...
... 
Ellipsis
>>> with sr.AudioFile("english.mp3") as source:
...   ...
... 

Expected behaviour

No error
