Optimization loop chassis (#181)

* adding experimental jupyter notebook in experimental/

* updated all calls and nu test to include loss method arguments

* removed invalid includes from collection and directly added to chassis.py;

* flake8 configured to ignore E501(some lines longer than 80) and E203(conflicts with black)

* moved chassis loop to MuyGPyS/optimize/experimental and updated __init__.py

* add notebook for distance function testing

* added updating neighborhood with learned length scales each loop iteration

* add parameter and code that allows reuse of optimizer instance over loop iterations

* added test for anisotropic distance function

* updated chassis workflow when reusing optimizer and update notebook with experiment and 4 treatments

* returning the nn lookup for inference

* added workflow tests determining where learned hps applied in opt loop and troubleshooting inference results

* added inference outputs test

* added training and inference results to tables in notebook

* refactored sample_batch call to to make workflow understandable, added time and probe count measurements, and added tables for training and inference results and a side by side plot of residuals

* added Abseil unit test to github CI

* Added another treatment single step + that computes an equal number of explore and exploit points
