Please add FLAC support

[CHJ85]

Hi there. Most of my songs are in flac format.
It'd be nice to have flac support.
Is this doable?

It seems to be pretty straightforward to do this: librosa can accept FLAC files directly. You would only have to modify the code to also scan for flac files

In Mp3ToVec.py:
if filename[-3:].lower() == 'mp3' or filename[-3:].lower() == 'm4a':
->
if filename[-3:].lower() == 'mp3' or filename[-3:].lower() == 'm4a' or filename[-4].lower() == 'flac':

Be careful as there are be parts of the code that assume that the extension is only 3 characters rather than 4 - e.g., full_path[:-3]
