Update to new Beakerx

[hadim]

Trying to update to twosigma/beakerx@45ed2ca

Some breaking API changes were trivial. But after that, the kernel doesn't work:

[INFO] Log level used is : info
[INFO] Scijava Kernel is started and ready to use.

Hi this is something we are about to take out. I could give a long explanation of what it's about but it doesn't really matter, it was a mistake and we are in the final steps of removing it: twosigma/beakerx#5434

should be early next week. if you want to just work around it, make this one line change to this constructor:

  public EvaluatorManager(KernelFunctionality kernel, Evaluator evaluator) {
    this.kernel = kernel;
    this.evaluator = evaluator;
    evaluator.startWorker();
    this.codeExecutor = this::execute;
  }

The update is not urgent. I just wanted to keep up with the base kernel. I can wait until next week.

Working now.
