The unsharding script currently requires us to pass in the checkpoint type, but this is not necessary since it can be read from config. Passing in the type has been a nuisance in the past, so this PR changes the script to default to the checkpoint type in the config. It changes the unsharder to use
build_sharded_checkpointer
, so that we don't need to duplicate that logic in the unsharding script.Currently untested.
