Improve logging in main and around sig scanning

[ff14wed]

This PR also adds some refactors to clean up the unused code and to avoid code duplication.

It adds logging for the signature used, the time spent scanning signatures, and emits logs at various parts of the lifecycle to aid in debugging.

Fixes #10

Here are what the new logs look like:
