Terminal settings not restored after panics/crashes #1459
Description
Describe the bug
When the application exits abnormally (crashes or panics) the terminal is left in a broken state. Basic shell interactivity is lost: typed commands are not echoed (reflected as I type), line alignment is completely chaotic, and the general usability of the terminal is severely degraded. This persists until I explicitly run stty sane or a similar to restore the expected settings. Abrupt interruptions have to be handled by the user.
For the sake of documentation these are all the options that are off after exectution:
stty brkint ignpar icrnl ixon opost isig icanon iexten echo
I am using Bash via terminator emulator on manjaro. Also applies to xfce terminal.
To Reproduce
set up a crash or a panic during the tea program execution. out-of-range Index work well.
Source Code
I noticed that the panics are handled with tea.program.recoverFromPanic() link. I count not find a execution route from there into restoreTerminal(); perhaps the solution would be to add it to panic handling.

Additional Context
I know... I know... it would be more logical to not have my program crash or panic. I'm trying, ok?
