Support Filtering Logs and Content by Package Name

We are migrating build-systems and plan to use Diffuse for comparison between two APKs built by different build systems (Buck and Bazel). As part of this, some formatting in the output to account for significant content helps with parsing since the list of files that are different would be enormous.

Is this a use-case you'd be interested in us upstreaming?

The issue names no files, tests, or entry points. First inspect Diffuse's existing command output for APK comparisons and clarify the desired package-name filtering and significant-content formatting; done should mean the requested filtering is defined, implemented, and verified for the stated Buck-versus-Bazel comparison use case.
