Deserialization errors for publisher and subscriber options are not catched

[elBoberido]

Required information

The deserialization of the publisher and subscriber options don't handle invalid values for enums like SubscriberTooSlowPolicy correctly and the deserialized struct could end up with an invalid enum value.

Operating system:
all

Compiler version:
all

Observed result or behaviour:
An integer value is converted into an invalid enum value, e.g. 42 into an enum having only 0 or 1 as valid value

Expected result or behaviour:
Invalid values should be catched when deserialized

Conditions where it occurred / Performed steps:
Request a publisher port from RouDi and send e.g. 42 as value for the subscriberTooSlowPolicy.
