Enhancement: Improvement to state system

[cjavad]

To address certain issues:

• Fix partially cleared events (has_changed) removing the dirty event and never getting retriggered.
• In combination with intervals when a value is only pushed when it is changed we need a way to automatically re-dirty an event after the interval has passed.
• When a field is a float, but it is only sent as a integer, either support floored diffing or conversion to not trigger events when the proposed value is actually the same as the last sent value in reality. (Ei. temperature)

Rework internal state system to make printer status more efficient and accurate and prevent bugs long term. See the state_effect branch for a WIP model.
