Fix duplicate downloads

[matejchalk]

Should fix various JSON.parse errors in monorepo mode when downloaded artifacts from previous run are read by compare command. The artifacts are downloaded in parallel, so may conflict with each other. The requests to GitHub API are also duplicated for each project - replaced with in-memory cache of downloaded files.
