Add tickn method to redpiler JITBackend trait

[BramOtte]

Adds a method called tickn to the redpiler JITBackend trait which executes multiple ticks per call instead of just one

While right now the overhead of going through all the abstraction layers is minimal there is still a very small overhead.
But more importantly allowing the backends to have their own implementations can allow for other backends to do specific optimizations.
For example a threaded backend could have parts of a circuit be slightly out of sync if this doesn't effect the functioning of the circuit and then sync back up at the end.
Or ticks could be skipped if no ticks are in the queue.
