#90 [WIP] adds AttributeMonitor and AliasedStringAttributeMonitor for managing the metadata attributes and issuing attribute change requests, so that we can remove attribute management code out of the decoder states. Adds heuristic tracking with the monitor so that we can better track the talkgroups and other attributes and smooth out the rapidly changing values when we're decoding a weak signal. This will eventually close out issue #101
