Pull Request Overview

This PR refactors and modernizes certificate parsing APIs for x509 to improve consistency and inline performance.

• Unifies function signatures to accept Into instead of AsRef<[u8]> for more flexible certificate input.
• Introduces helper functions (parse_cert/parse_certs) and inlines functions for performance.
• Updates error handling and wraps certificates in a new Certificate type.

• [nitpick] The parameter '_certs' is used later in the function call but is prefixed with an underscore, which typically indicates an unused parameter. Consider renaming it to 'certs' for clarity.

• [nitpick] The parameter '_certs' is used in the function despite the underscore prefix, which might mislead readers to think it is unused. Renaming it to 'certs' would improve code clarity.
