- Added option to set the filename for single file downloads
- Changed the number cli arguments to unsigned, since they can only be
positive anyways
- Combined the cli arguments into a struct
- Zippy URLs are now resolved directly before starting the downloads
- Resolve errors now should print the error to the top-log and skip the
file. (untested)
- The status reports are now sent after either 5M download or 1s
- Fixes#10, #4
