setup.sh to check host for running out of disk space when setting up new model

[tstescoTT]

When downloading all weights, repacking, tt-metal caches - it's not uncommon for the user to need to manage their storage capacity. Having the setup.sh script fail during download, repack, for the model crash during tt-metal cache generation because the host runs out of disk space is a nuisance to debug.

Possible solution:
The setup.sh script can check for a minimum amount of required disk space for each desired model.
