xdg compliance

Describe the bug
parllama uses ${HOME}/.parllama as a storage

Expected behavior
parllama should store, for example, .parllama/cache/ in ${XDG_CACHE_HOME}/parllama/ which should default to ~/.cache/parllama/ if this env variable is missing. settings.json is a config file. and so on

there is a way you can implement it without breaking anything. could not find any public references implementing migration, attach later if needed

i've not checked parllama file locations on other OSes, consider checking them too. apple specs have it's own locations to store things.

Parllama uses ${HOME}/.parllama on all OSs.
I will look into OS specific specs and migrate existing locations to the correct locations.
This will be in the next Parllama release, which I hope to have out in the next couple of weeks.
