Refactor proposal: deduplicate language “coverage” CLI boilerplate (Go/Rust)

[kunalsz]

Issue / current state

The Go and Rust language coverage utilities (floss/language/go/coverage.py and floss/language/rust/coverage.py) contain near-identical CLI boilerplate: argument parsing , logging setup, and PE validation via pefile. This duplication increases maintenance cost and creates risk of subtle drift

Why this refactor is needed

• Single source for shared CLI behavior reduces bugs and review overhead
• Makes future language additions easier and more consistent.

How it will be done

Introduce a small helper module (floss/language/cli_common.py) that provides:

• a function to add common argparse option
• a function to configure logging consistently
• a helper to open/validate PE input

@mr-tz Looking forward to your insights!

this could definitely be useful, esp. when in the future we would want to add support for ELF/Mach-O's into go/rust string extraction. I could take a shot at this if no one else is.
