Fingerprinting problems

[mhkarimi1383]

Describe the bug
I'm using sudo rs for while and I'm having some issues with fingerprinting

I'm using it in NixOS (master branch of nixpkgs)
And I have two problems and one recommendation

1. When scanning/waiting for fingerprint, Control-C will not work and I have to force kill (-9) or use Control-Z
2. When sudo-rs crashes (specially in the middle of the scan), fingerprinting will not work until I restart
3. For things like fingerprinting it should use a master process that others reuse the same fingerprint connection or session

To Reproduce
Steps to reproduce the behavior:

1. Install 'sudo-rs'
2. See error (See 3 items on top)

Expected behavior
Clean exit

Environment (please complete the following information):

• Linux distribution: NixOS (master branch)
• sudo-rs version [sudo --version] or commit hash: 0.2.13

Additional context
Add any other context about the problem here.

Which sudo-rs version? And is this pam_fprintd or some other fingerprint login implementation?
