Upload during hashing

It'd be nice to be able to start upload before the file is fully hashed with UP2K uploader.

Use case: big file is uploaded, we do not care about dedups, but just need file resume option, so if file exists - chunks should be checked one by one instead of waiting for the full list to be created. It's extremely useful with slow devices the file is being read from (usually I receive files like 80-200GB each).

Considering dedup - if file exists and is the same size - first and last (and middle?) few chunks could be checked separately, and then full file hash will be scheduled after non existent (not yet uploaded) files if everything is OK.
