* chore: move mod downloading to cli/cache * feat: data providers, ficsit and local * feat: keep cache in memory, load on init * feat: log invalid cache files instead of returning error * chore: make linter happy * feat: fill cached mod Authors field from CreatedBy * chore: make linter happy again * feat: add icon and size to cached mods * feat: cache the cached file hashes * fix: change to new provider access style --------- Co-authored-by: Vilsol <me@vil.so>
