Add a new dependency of `anyhow` crate, to use flexible concrete error handling mechanism, instead of the native error types.

To follow error handling convention of anyhow, insert `.context` to add detailed message of error context when returning from functions. In case of an immediate error exit, use a `bail!` macro. Note, main functions and unit tests stay untouched if possible.

There was a problem hiding this comment.
Some improvements would be good: Instead of writing errors to the terminal from functions that return Options it would be better to return Results.
Also, the dummy signature error is printed too prominently, we skip over it but it looks like the program crashed if you don't pay attention to the last line
Parsed and verified signature data from file "/var/tmp/outdir/.unverified/oem-ami.gz"
which indicates that it was successful.

Doing it in a follow-up is better, thus the approval. |

Thanks. I created a separate issue for the improvement of error handling. #28 |
