Support import configuration

**Description**
Currently lib lacks proper logging support.

**Proposed solution**
Add configurable logging with sensible defaults.

**Priority**: Low/Medium

Start by inspecting the lib directory and the existing configuration and logging entry points. The issue does not name a file or test, and its title refers to import configuration while the description asks for configurable logging. Done means the intended configuration behavior and sensible defaults are defined and implemented, with any relevant existing checks updated.
