Set `--save` and `--preserve` flags by default

[Masqueey]

In my case the process was interrupted and thereby lost any progress made. The cracked keys were added to my library, but before I could continue cracking, I had to rescan the entire card again. Why are these not set by default (or set to save the progress if interrupted)? Could these be set by default?

You interrupted by yourself? I don't remember if it will remove nonces unless full recovery is competed. Will check.
--save and --preserve are debug flags and won't be enabled by default.

Yes, just ctrl+C'd the process, but expected to be able to continue from there. Maybe that is intended behavior though.

Checked code, not intended. Will fix, won't remove nonces if user quits app
