Ability to resume an upload / download

[drmaas]

@hierynomus if you're interested, I may be able to contribute a feature to be able to resume failed uploads and downloads. This is useful for very large files that encounter frequent network interruptions.

I have something working locally and would be able to put out a PR once I work out the kinks.

I would be interested in your branch and providing feedback as well. I'm using SSHJ to put/get large files frequently and connection issues have been troublesome from time to time. Breaking the files up into chunks or finding a different solution is something I wasn't looking forward to tackling.

@drmaas @hierynomus Any hope for this reaching the masses?

[brenttyler]

Please, if there's any chance of this being officially supported or if I could be a beta tester, I am happy to help.

I created a PR for this: #775

@hierynomus has merged my PR #775 into master!
