Should this look for the latest common migrated snapshot? We don't just want to find the latest common snapshot, we want to find the one we know for sure was migrated last. WDYT?

no, i don't think so, i think we just want to bring over everything since the latest common
if we make holes we can fix them manually, we want this whole process done in the next day or so

i think the main thing is to keep the files, and snapshots, and to have each filename labeled by date range so that the data is all available for reruns

This script will
find the latest common snapshot between go-ipfs and c1 nodes
create a new snapshot on go-ipfs and send to c1 node
on c1 node, generate a list of modified blocks
run the migration on the list of modified blocks and track errors
the c1 migration logs are piped to a file and include checkpointing
