Add configuration options for compression

**Problem**
When working with config, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

Start by locating the configuration parsing and compression-related entry points in the Shell code, then read the existing error paths and available checks. Clarify whether the intended result is configurable compression, more descriptive configuration errors, or both; done should include defined options and verifiable, detailed error messages.
