Fix: do not fail when hf cache location contains unparseable paths

[av]

Currently, speaches fails to load TTS models when HF cache contains custom files that do not follow the -- schema, this small fix skips over such files altogether, similarly to .locks

Thx for the change. Could you just provide one example of such path

[av]

I use a lot of different inference engines and tools revolving around HF, a few examples from my local HF cache:

ls ~/.cache/huggingface/hub/
tmpd3p2ua2d
tmphejj1on8
tmphejj1on8
version.txt
datasets
metrics

Not all tools are playing with the cache nicely, relying on only native set of file present means that some other tool might break speaches unexpectedly (exactly what happened in my instance due to the files above)

[fedirz]

Makes sense. Thx for creating the pr
