Code Releases Wiki Activity

Parse new version of Pebble health datalog message with tag "84".

Browse Source 
This message was previously treated as a further "Sleep" message type, with firmware version 3.12 further types were added that are clearly unrelated to sleep (possibly to high-intensity activities like running etc.), hence the related code is now moved to a separate class.

The only decoded records are still sleep-related.

Fixes #312
