Enhancement: Providing premature exit option for CLI

[carmen-chau]

Look into whether implementing a feature where a user can prematurely exit the CLI prior to reaching the prompt that appears right before transcription/translation appears:

Do you want to start the process? If not, this app will quit.

Currently, if the user wishes to terminate CLI prior to this process, they would have to press CTRL-C 2-3 times to exit (the program also throws errors due to interrupted termination)

Possible implementation ideas:

• For each step in the CLI, have an exit option (ie: Add a "exit" option for each "choice" for each prompt). This would be extremely tedious to do, but I cannot think of better options (since at the moment, the CLI doesn't really allow spontaneous user input)

@moonsdust thoughts about this issue? I think we should run it by the STREET team to see if this is a pressing issue to address, and how we can approach it.

@carmen-chau In the PR I made, I added in different ways the app can exit with throwing errors. But I had it so that for the list-type prompts, there's an option to exit the app and for the input-type prompts, users can just use CTRL-C to exit the app and it shouldn't throw an error (hopefully).
