CTRL+C sequence does not exit the program when in process

[sagisar1]

Hello, I have seen when using jwt_tool.py, that when you hit CTRL+C , the program is not existing, and actually you are forced either to close the terminal tab or to wait until the program finishes.
this is an enhancement feature I suggest, that would it make more comfortable for the use of the tool

an example image is provided to simulate the issue:

Either try CTRL+C a few times, or CTRL+Z then type kill %

@rbrown256 CTRL +C few times doesn't work (I tried), and I know about CTRL + Z, , but this is just a workaround. The appropiate solution would be to solve that issue by inspecting the code to see why it happens, and hence I opened this issue.
