Add a `dir: &Path` parameter to `download_many`. On entry it skips all downloads if `dir/.success` already exists; on success it writes that marker so subsequent runs skip the whole batch. Call sites updated: clickbench partitioned, public_bi bzips, vector_dataset train shards. Signed-off-by: Joe Isaacs <joe.isaacs@live.co.uk>
