ipsw dl dev - add more docs about error cases

[benjaminRomano]

What happened?

I'm hitting the following error message:

   ⨯ failed to login: failed to sign in; expected status code 409 (for two factor auth): response received 401 

Running the following command:

ipsw download dev --os --json --pretty --output . -V

The issue is that I put the wrong credentials in. I had to manually go into Keychain Access to remove the invalid entry. To know to do that I had to look through the source code. it may be helpful to improve the diagnostic error message in this case.

e.g. include the response message in the output (only shown with -V).

Additionally I ran into a problem where once I had the correct credentials Apple was not sending me a verification code. On the website, I need to manually have it send SMS verification code. I'm not sure if it's possible to do that programmatically from the CLI though.

How can we reproduce this?

Insert invalid username / password and run dev download command.
