cPickle fails to load cache file, raises exception.

[JoseIgnacioTamayo]

I have this pluging on an OSMC system, with Kodi 18.

It has happened that for some reason cPickle is not able to load the cache file for Artists, raises an exception and does not allow the plugin to show the Artists menu. I solved this by either deleting the cache files or just catching the exception and letting go

.kodi/addons/plugin.audio.deezer/resources/lib/cache.py", line 24, in read_cache
                                                self._cache = pickle.load(self.file)
                                            UnpicklingError: invalid load key, 'v'.
