Protontricks exits 0 on failure

Describe the bug When installing vcrun2019, which usually fails due to sha256 mismatch, protontricks exits zero when it should exit with a non-zero code. I'm unsure whether this bug affects other scenarios or not.

To Reproduce Steps to reproduce the behavior:

Run command protontricks 489830 vcrun2019
Command fails but exits 0 anyway

Expected behavior Command should exit with a non-zero return code since it failed to complete

System (please complete the following information):

Distro: Arch Linux
Protontricks version: 1.6.1
Steam version: Beta

Additional context

I'm writing a script which configures Bethesda games for modding, and this issue breaks the return logic for installing verbs.
