Downloading files when tile is already downloaded.

[Gert Sterenborg]

Hello Olivier,

Thank you very much for creating this tool!

I have the issue that my internet connection is very slow, so I want to minimise the amount of bites send/received. That's why I only use the -t option.
When you try to download a complete download for the second time, it is skipped. But this is not working when using the tiles/granule option.
