Applets do not respond to keyboard interrupt

[daniel-riehm]

KWIVER applets called on the command line cannot be interrupted by pressing Ctrl-C. This should be the default behavior, so we must be catching SIGINT somewhere.

Tested on Ubuntu 20.04.

Hey there,

I've been trying to replicate the issue you mentioned with the Ctrl-C not interrupting KWIVER applets on Ubuntu 20.04, but so far, it seems to work correctly for me.

To get a better understanding of what might be going wrong, could you share some more context about this problem? Anything specific about your setup or the steps you take leading up to the issue might shed some light on the situation, the exact applets or command-line options active when the issue arises.

No special context, just using e.g. bin/kwiver dump-klv <args>, or bin/kwiver transcode <args>.
