Details of the Error struct

Without these, the Error struct is just a code u8.

• error_unprocessed_coap_option — Allow storing the RFC9290 “Unprocessed CoAP option” problem detail in Bad Option errors, and emit it in CBOR payloads. If this feature is not enabled, any such detail provided in errors is silently not emitted.
• error_request_body_error_position — Allow storing the RFC9290 “Request Body Error Position” problem detail in Bad Request errors, and emit it in CBOR payloads. If this feature is not enabled, any such detail provided in errors is silently not emitted.
• error_max_age — Store a Max-Age of the error. The method Error::with_max_age() is only available when this feature is enabled.
