- What was broken was that it would just play activity from the first page view, but then would stop at the second page view (meta) as actions after that had been discarded
- This restores the functionality given by the comment 'return the events from last meta to the end.' - we never want to discard events that are after the baseline time
- I believe 'session' is the incorrect terminology for this function name, as a session in web analytics usually means a series of page views
* Move mutation processing into it's own object.
This should stand on it's own as a refactor, but is intended as a basis
for exposing the new MutationBuffer object to further outside control e.g.
to 'mute' or batch up mutation emission when the page becomes inactive

point of view
* The `processMutations` function needed to be bound to the `mutationBuffer` object, as otherwise `this` referred to the `MutationObserver` object itself
* Neglected to add this output of `npm run typings`
* Get around the binding problem by using Arrow function expressions
* Prettier formatting
* introduce pako and add general packer interface
* add tests for packer
* use function API instead of class API for better tree shaking support
* refcatoring the rollup bundle config
1. add a liveMode flag to config, when liveMode is set, the timer
will keep running even though all the actions casted
2. add a public method addEvent, which will cast newly added event
in sync
3. move mouse in sync mode with the latest position info
