Fixes dictionary selector bit when encoding/decoding complex annotations

[ahrytsen]

Fixes #33

[bnatrajan]

@ahrytsen, as indicated in the issue, there is a need for a new bit to indicate a 'top-level annotation'. This will be available as part of RDE 1.1.

The changes in this pull request will break annotations with complex objects that don't use a top-level annotation. As an example:

 {
   "@Redfish.CollectionCapabilities": {
      "Capabilities": [
         {
            "CapabilitiesObject": {}
         }
      ]
   }
}

@bnatrajan, haven't understood this: "annotations with complex objects that don't use a top-level annotation". In your example there is a top level property "@Redfish.CollectionCapabilities"....(and it should have bit) Inside "CapabilitiesObject": {} should be "@odata.id" which is also from top level and should have that bit as 1.

@ahrytsen, how about the "Capabilities" property itself? This must also have the annotation bit set. Also the annotation bit needs to be set for the "CapabilitiesObject" property as well.
Essentially all nested properties within an annotation property will need to have the bit set.
