How should we handle unparsable listOfValues?

[baardl]

When a part of the hexString with BacNet Octets can not be parsed into something this library understand we need to flag this to the client.
Also we want to trace this behavior to be able to implement updates solving these issues.

Test Code:
https://github.com/entraeiendom/bacnet-2-json/blob/8d302caad3c4c0fc86bd12666bc26f1b4fca016a/src/test/java/no/entra/bacnet/json/observation/ObservationParserTest.java#L26

Affected code:
https://github.com/entraeiendom/bacnet-2-json/blob/8d302caad3c4c0fc86bd12666bc26f1b4fca016a/src/main/java/no/entra/bacnet/json/values/ValueParser.java#L104

static Object findValue(ApplicationTag applicationTag, String valueHex) { Object value = null; int type = applicationTag.findType(); switch (type) { case INT_VALUE: int intValue = toInt(valueHex); value = Integer.valueOf(intValue); break; case REAL_VALUE: float floatValue = toFloat(valueHex); value = Float.valueOf(floatValue); break; default: value = null; //Alternative: //value = "#" + valueHex; } return value; }

Observation observation = observations.getObservations().get(1); assertEquals("StatusFlags", observation.getName()); assertEquals("0400", observation.getValue());
