Check for Engine attribute missing

[mlenkeit]

Describe the bug

There is currently no check for the value of the Engine attribute of a rule:

dgc-certlogic-ios/Sources/CertLogic/CertLogic.swift

Lines 51 to 70 in 14bcdce

	rulesItems.forEach { rule in
	if !checkSchemeVersion(for: rule, qrCodeSchemeVersion: qrCodeSchemeVersion) {
	result.append(ValidationResult(rule: rule, result: .open, validationErrors: [CertLogicError.openState]))
	} else {
	do {
	let jsonlogic = try JsonLogic(rule.logic.description)
	let results: Any = try jsonlogic.applyRule(to: getJSONStringForValidation(external: external, payload: payload))
	if results is Bool {
	if results as! Bool {
	result.append(ValidationResult(rule: rule, result: .passed, validationErrors: nil))
	} else {
	result.append(ValidationResult(rule: rule, result: .fail, validationErrors: nil))
	}
	}
	} catch {
	result.append(ValidationResult(rule: rule, result: .open, validationErrors: [error]))
	}
	}
	}
	return result

Expected behaviour

If a rule has the attribute Engine with a value other than CERTLOGIC, the rule is not evaluated but reported as open.
