ot::TimeTicker class
Represents a time ticker. The time ticker emits periodic ticks (with 1 second period interval) to a set of registered tick receiver modules. The tick receivers (OpenThread objects) are identified by the `Receiver` enumeration. The receiver objects must provide `HandleTimeTick()` method which would be invoked by `TimeTicker` periodically.
