This change replaces the use of `CoroutineContext` for passing the
`SimulationDispatcher` across the different modules of OpenDC by the
lightweight `Dispatcher` interface of the OpenDC common module.

This change updates the `SimulationScheduler` class to implement the
`Dispatcher` interface from the OpenDC Common module, so that OpenDC
modules only need to depend on the common module for dispatching future
task (possibly in simulation).

This change adds support for converting a `Dispatcher` implementation
into a `CoroutineDispatcher` instance.

This change updates the build configuration to use Spotless for code
formating of both Kotlin and Java.

This change updates the repository to remove the use of wildcard imports
everywhere. Wildcard imports are not allowed by default by Ktlint as
well as Google's Java style guide.

This change renames the method `runBlockingSimulation` to
`runSimulation` to put more emphasis on the simulation part of the
method. The blocking part is not that important, but this behavior is
still described in the method documentation.

This change updates the implementation of `SimulationDispatcher` to use
a (possibly user-provided) `SimulationScheduler` for managing the
execution of the simulation and future tasks.

This change updates the TimerScheduler implementation to directly use
the Delay object instead of running the timers inside a coroutine.
Constructing the coroutine is more expensive, so we prefer running in a
Runnable.
