Lately, fetching the files required to update pangolin lineage information from GitHub has been flaky and unreliable. This PR lets the user download the required files manually (alias_key.json and lineages.csv), and then update from these local files, instead of only allowing the updates from web downloads.
Also added logging output that includes the url where these files can be downloaded, in case that download fails. This lets the user know where to download the files that are needed, which can then be used to update manually.
