[BUG] Memory Leak

Hi, thank you for making this very useful project, it’s really awesome.

I’m experiencing a suspected memory leak during my use.

When load a large batch of songs, I can see the memory usage slowly growing.

I’d like to ask you if there are any areas I can look at to help locate a fix for this memory leak?

My environment is Ubuntu 20 and python 3.8.

sample code:

import sys

from librespot.core import Session
from librespot.metadata import TrackId
from librespot.audio.decoders import AudioQuality, VorbisOnlyAudioQuality

account_user = ''
account_passwd = ''
session = Session.Builder().user_pass(account_user, account_passwd).create()


def load_data_from_spotify(track_id):
    spotify_track_id = TrackId.from_uri('spotify:track:' + track_id)
    stream = session.content_feeder().load(spotify_track_id, VorbisOnlyAudioQuality(AudioQuality.NORMAL), False, None)
    audio_buffer = stream.input_stream.stream().read()

    # dosomething

Yes, that is because the buffer has not been released.
