Resume is not a valid parameter anymore

[KevinPassemard]

In the readme, we can see in the options liste :
-R, --resume Do not overwrite existing files

This is not a valid option anymore, when typing -R or -resume in a command, i personnaly get the error :
unrecognized flag --resume or unrecognized flag -R.

When asking for the list of options available directly in the compiled version (with the -h parameter), we get a list where no resume option could be found.

I think this parameter should be remove from the readme or repair directly in the source code. But not left like this wich is miss-leading (and i personnaly lost 5 hours of processing because of that).
