Cache fsspec downloaded files

Looks good to me, but this won't actually change the behaviour of say this file

TTS/TTS/tts/utils/managers.py

Line 323 in 53f07f4

self.encoder_criterion = self.encoder.load_checkpoint(

as long as we don't enable it by default or where it would be usefull right?

@WeberJulian yeah I think cache should be explicitly set true for all calls of load_checkpoint if it is what you mean.

My question is should we enable it by default for managers.py or maybe expose a flag that does it for this script?

I don't think its a good idea. We could be using the same model without knowing it since the model file name is the same.
